Gout Frequently Flares In Your Knee But You May Not Always Know That Your Knee Pain Is Due To Gout Heres How To Tell Since Prompt Treatment Can Reduce Your Risk Of Complications
Knee pain can be a common symptom of several types of arthritis, as well as many other conditions or injuries. If your knee stiffness is accompanied by a burning pain and is warm to touch, you may have a gout flare in the knee.
Though gout is most often associated with the big toe, gout tends to flare in areas that already have arthritis, says Robert Keenan, MD, a rheumatologist with Articularis Healthcare in Summerville, South Carolina. Although gout can strike in many different joints, as a general rule, gout works its way up the body. If its not treated, it works its way up from the big toe, through the ankle, to the knee, and then to the lower spine and so on.
Gout can affect both knees, but typically is felt more strongly in one knee say, where you may have arthritis wear-and-tear to begin with.

What Happens At Your Appointment
The GP may ask about your diet and if you drink alcohol.
They may refer you to see a specialist and arrange a blood test and scan. Sometimes a thin needle is used to take a sample of fluid from inside the affected joint, to test it.
The blood test will find out how much of a chemical called uric acid there is in your blood.
Having too much uric acid in your blood can lead to crystals forming around your joints, which causes pain.

Here are some treatments and pain management options you may expect for fluid on the knee: Aspiration Your doctor may drain the knee to relieve the pressure of the knee fluid. If blood is present, then it is often sent to the lab to analyze the fluid to ensure that infection is not present.

How Uric Acid Crystals Form
Infographic
The build-up of uric acid crystals begins with purines, a chemical compound found in many foods.
- When the body metabolizes purines, it produces a substance called uric acid.
- The uric acid enters the bloodstream.
- The kidneys filter the blood and normally filter out excess uric acid. This uric acid is then excreted via urine or stool .10
- If the kidneys cannot adequately filter out excess uric acid, or if the body produces too much uric acid, there will be too much uric acid in the bloodstream.
- Too much uric acid in the bloodstream is called hyperuricemia.
- In some people, hyperuricemia leads to the formation of uric acid crystals that collect in joint tissue, leading to painful symptoms.
An inability to adequately process and excrete uric acid accounts for an estimated 90% of gout cases.9 Other cases occur because a body produces too much uric acid.
What Are The Causes And Triggers Of Gout In The Knee
The buildup of uric acid in the body is known as hyperuricemia. Your body produces uric acid when it breaks down purines. These are compounds found in all your cells. You can also find purines in several types of food, especially red meat and some seafood, as well as alcohol and some sugar-sweetened drinks.
Usually, uric acid passes through your kidneys, which help to eliminate extra uric acid in your urine. But sometimes, theres too much uric acid for your kidneys to handle. In other cases, the kidneys cant process typical amounts of uric acid due to an underlying condition.
As a result, more uric acid circulates throughout your body, ending up in your knee as uric acid crystals.
4 percent of adults in the United States. It tends to be more common in men because women usually have lower levels of uric acid. But after menopause, women start to have higher uric acid levels. As a result, women tend to develop gout at an older age than men do.
Experts arent sure why some people produce more uric acid or have trouble processing it. But theres evidence that the condition is often genetic.
Other things that may increase your risk of developing gout include:
- consuming a lot of high-purine foods
- consuming foods and drinks, especially alcohol, that increase uric acid production
- being overweight

Why Do My Joints Pop When I Bend My Knee
Over time, gas can build up in the areas surrounding the joint, forming tiny bubbles in the synovial fluid. When you bend your knee, some of the bubbles burst, and ligaments may snap or pop. This is normal, and happens to everyone from time to time. Arthritis, on the other hand, damages cartilage and bone.
Reducing Uric Acid Levels
Tip: If you really enjoy seafood, there are a few options that are low in purine, such as salmon, mahi mahi, snapper, and tilapia. These fish shouldnt raise your uric acid levels.XResearch source

How Will Gout Affect Me
Attacks can vary from person to person. Some people only have an attack every few years, while others have attacks every few months.
Without medication attacks tend to happen more often and other joints can become affected.
Having high urate levels and gout for a long time can lead to other health problems, including:
- narrowing of the arteries – which can lead to an increased risk of stroke or heart attacks or other heart problems
- osteoarthritis, which occurs when the urate crystals and hard tophi cause joint damage.
- an increased risk of developing kidney disease or worsening of the condition if you already have it
- kidney stones
- an increased risk of some cancers, especially prostate cancer
- mental health problems, including depression
- underactive thyroid
- erectile dysfunction in men.
If you take medication to lower your urate levels, and have a healthy diet and lifestyle, most of the damage and complications caused by gout can be stopped.
Treatments for gout are incredibly successful. There are two main parts to treating gout, which are:
- treating the acute attack
- treatments to prevent future attacks.
Acute Attack Pain Management
Home remedies. Reducing inflammation during an acute gout attack will provide pain relief.
- Ice. Apply ice to the affected area to reduce swelling. Do not apply ice directly to the skin. Use an ice pack or wrap a towel around the ice. Apply ice for about 20 minutes at a time.
- Elevate. Frequently raise and keep the affected area above the level of the heart.
- Rest. Move the affected area as little as possible while symptoms are present.
- Over-the-counter non-steroidal anti-inflammatory medicines. If the gout attack is mild, anti-inflammatory drugs available without a prescription may relieve pain. Because there are serious side effect of using non-steroidal anti-inflammatory drugs even the over-the-counter strength be sure to check with your doctor before taking them.
Prescription medications. Your doctor may recommend a prescription-strength non-steroidal anti-inflammatory medicine such as indomethacin.
Colchicine is also given to reduce inflammation during an acute gout attack. This drug has recently been approved by the Federal Drug Administration for treatment of gout. Like all medications, colchicine has side effects that you will need to discuss with your doctor.
Your doctor may also prescribe corticosteroids for acute gout attacks. These are strong anti-inflammatory medications that can be taken either in pill form, intravenously, or injected into the painful joint. Cortisone may improve the severe inflammation very quickly.

How Is Pseudogout Diagnosed
Your doctor may draw fluid from your joint to check for the crystals that cause pseudogout. X-rays might also show some buildup of crystals or signs of joint damage. Your doctor will probably want to rule out other possible causes of your symptoms, such as gout, osteoarthritis, or rheumatoid arthritis.
What Does Gout Look Like
Too much uric acid in the blood causes gout. Uric acid is a byproduct of the breakdown of purines. Generally, purines are produced by the body, but we also get purines from diet. As purines are broken down, uric acid crystals are produced. These small uric acid crystals build up in joints. The big toe is affected but other joints such as the ankle, knee, and patella are also be affected.

Can Pseudogout Be Prevented Or Avoided
Treatment can relieve the symptoms of pseudogout and slow or prevent damage to your joints. Unfortunately, no treatment can get rid of the crystal deposits that cause pseudogout. Taking low doses of colchicine may help to reduce your risk of future attacks. Your doctor can talk to you about the risks and benefits of taking this medicine.
If another condition, such as a thyroid problem, caused your pseudogout, treating that condition may help to make the symptoms of pseudogout less severe. It may also make flare-ups less frequent.
The Role Of Medication In Prevention Of Gout
Table 3: Medications to pevent attacks of gout
Standard medications in preventing gout attacks
i. Colchicine : using the matches analogy discussed above1, using colchicine can be seen as dampening the uric acid matches. Colchicine does not lower the bodys store of uric acid, but it decreases the intensity of the bodys inflammatory reaction to these crystals. Recent studies have shown that at least one mechanism of colchicines action is by acting to prevent a cascade of reactions that lead to the production of interleukin 1-beta, which is an inflammatory protein , which is important in gouty inflammation.8
ii. Allopurinol: This agent is presently the most commonly used drug for the prevention of gout. Allopurinol blocks the enzyme xanthine oxidase, which blocks the breakdown of purines, thus decreasing the bodys total amount of uric acid. Allopurinol is effective in preventing gout no matter what the mechanism of the elevated uric acid was. Whether a person is making too much uric acid, or has difficulty excreting it via the kidney, allopurinols decrease in uric acid production leads to the same goal: a decreased total body uric acid.

The Role Of Uric Acid
Uric acid is produced when your body breaks down purines, which are substances naturally found in your body, as well as in protein-rich foods. At normal levels in your blood, uric acid is a powerful antioxidant and does not cause any damage. The body keeps uric acid at a set level by excreting it through the kidneys and in urine.
It is possible to have hyperuricemia and not develop gout. About two-thirds of people with elevated uric acid levels never have gout attacks. It is not known why some people do not react to abnormally high levels of uric acid.
When To Contact A Doctor
People who are experiencing symptoms they think might be due to gout should seek guidance from a doctor.
Gout tends to progress and worsen over time. However, early treatment can often help control gout and reduce the risk of severe complications, such as joint damage.
People with gout can also develop infections, which they need to treat as soon as possible. Those who have diabetes are more likely to develop infections with gout.
A person should seek emergency medical care if signs of infection are co-occurring with symptoms of gout.

Diagnostic Evaluation Of Gout In Foot
What goes into a gout diagnosis? These procedures are options:
- Joint aspiration. Fluid is withdrawn from the joint and inspected for crystals and bacteria.
- Blood tests. White blood cell count, ESR , triglycerides, and kidney function may be elevated.
- X-ray. An x-ray of the affected joint is likely to appear normal during an initial acute episode, but in chronic gout, bone erosion and overhanging edges may be seen.
Whats The Outlook For People With Gout
Untreated gout can lead to permanent joint damage. The buildup of uric acid in the joints and soft tissue is called tophus. Some people with gout can also develop other health problems, such as severe arthritis, kidney stones and heart disease. Its important to discuss your symptoms with a healthcare provider.

The Role Of Physical Activity In Prevention Of Gout
Along with diet, physical activity can help with weight loss, and gout has been associated with being overweight.7 in patients with well-established gout, especially if X-rays have demonstrated joint damage in the foot, a low-impact exercise program is reasonable. An exercise program combined with diet in gout can reduce risk for attacks.7 If an attack seems to be coming on in the lower extremity, patients are well-advised to try to get off their feet, since impact seems to worsen gout attacks. Clues to an attack of gout coming on include local swelling, heat, redness, and tenderness in a joint, especially in the foot, ankle, or knee. Some patients have fever and chills as the first warning that an attack of gout is coming on.
Diagnosis And Treatment Options For Gout And Bursitis
Unless an infection is present, bursitis can be well managed through self-care. Its important to remember the acronym PRICEM when treating bursitis at home.
Protection Protect the area from future injuries by wearing padding.
Rest Limit the use of the joint and let it rest.
Ice Apply ice packs a few times a day, but not directly onto your skin.
Compression Wear compression bandaging to limit blood flow to the area as it contributes to swelling.
Elevation Keep the joint elevated if possible to prevent blood from pooling in the area.
Medication Take anti-inflammatory medication or antibiotics as instructed by your doctor.
In the rare instance, surgery may be recommended to drain the bursa in order to alleviate the inflammation.
Other treatment options include physical therapy, corticosteroid injections, and assistive devices like a cane.
Some preventative means for bursitis include protecting the joints from injury, either by wearing protective clothing or by modifying or avoiding certain activities. Take a moment to rest if you are performing repetitive tasks, always warm up prior to exercise, and build strong muscles to protect your joints.
Other preventative measures include maintaining a healthy weight, using kneeling pads, lifting objects correctly, wheeling heavy loads, avoiding sitting for long periods of time, and exercising regularly.

How Long Does Gout In The Knee Last
Gout flare-ups can last for several hours at a time, but you may feel pain in your knee for days or weeks. Some people only have one flare-up in their life, while others have them several times a year.
Keep in mind that gout is a chronic condition, meaning it lasts for a long time and requires ongoing management. Dietary changes and medications can make a big difference, but youll also be at risk of having a flare-up.
Keep in mind that it can also take some time to find the right combination of diet changes and medication that works for you. Dont be discouraged if things dont seem to be improving right away.
Comparing Bursitis And Gout Causes
Bursitis is a common cause of painful hips, knees, and elbows, but it can be managed with nonsurgical treatments. Bursitis occurs when the bursa a small, fluid-filled sac that acts as a cushion and lubricator for our bones, muscles, and tendons around our joints becomes irritated or infected, causing pain through movement. If bursitis is caused by an infection, then medical treatment is required. But if no infection is found, then medical attention can help prevent the condition from worsening.
A person has bursitis when inflammation of the bursa occurs, causing pain when moving.
Bursitis can affect any joint, including the hip, knees, shoulder, elbow, buttocks, and thigh.
The common causes of bursitis are injury, infection, or a pre-existing condition in which crystals form in the bursa.
Gout is a result of crystallized uric acid, which occurs when a person has high levels of uric acid in their blood. Uric acid results from the breakdown of purines found in some foods like red meat and alcohol.
Normally, uric acid passes through our systems and is released through our urine, but with excessively high levels, the uric acid can build up and crystallize in joints and surrounding tissues, causing discomforting symptoms.
