Lower Leg Pain Caused By Veins And Nerve Issues

1. Blood Clot

When blood thickens in veins, it can develop a clot. This typically happens in the thigh or lower leg, commonly leading to pain from knee to ankle. There is a higher risk if you are overweight, on certain medicines, or inactive for a long car ride or flight.

2. Varicose Veins

Varicose veins are caused by weakness in the vein walls or valves and can lead to a dull ache, particularly after standing.

3. Lower-Extremity Peripheral Arterial Disease

This occurs if your legs arteries get damaged and harden. The legs begin to miss needed blood flow, leading to pain or cramps when walking or climbing stairs.

4. Narrowed Spinal Canal and Sciatica

When the spinal canal narrows due to a herniated disc, arthritis of the spine, or another cause, it can lead to weakness, fatigue, numbness, tingling, or cramping, burning leg pain when you sit or stand. It may start in the hip and the back before extending down the leg.

5. Diabetic Neuropathy

This diabetes complication can be due to high blood sugar levels and leads to pain in both legs. It also features less sensation and numbness in lower legs.

When to See a Doctor

You should see your doctor for pain from knee to ankle if you have the following symptoms:

Are You Getting Any Other Symptoms With The Pain

The first thing we need to do is to exclude the red flags. Two potential causes of unexplained pain are infections and tumours. Emphasis on the word potential: these causes are unlikely, so we dont want to be alarmist. But a consultant will want to eliminate them. If your pain is severe, if it occurs particularly at night, if theres increased heat, redness or swelling in the knee these are good reasons to seek prompt medical advice.

What Can You Do For The Pain

Your plan will depend on your specific injury. Mild to moderate issues will often get better on their own. To speed the healing, you can:

  • Rest your knee. Take a few days off from intense activity.
  • Ice it to curb pain and swelling. Do it for 15 to 20 minutes every 3 to 4 hours. Keep doing it for 2 to 3 days or until the pain is gone.
  • Compress your knee. Use an elastic bandage, straps, or sleeves to wrap the joint. It will keep down swelling or add support.
  • Elevate your knee with a pillow under your heel when you’re sitting or lying down to cut down on swelling.
  • Take anti-inflammatorymedications. Nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen will help with pain and swelling. Follow the instructions on the label. These drugs can have side effects, so you should only use them now and then unless your doctor says otherwise.
  • Practice stretching and strengthening exercises if your doctor recommends them. You may want to do physical therapy, too.

Make an appointment with a doctor if you still have pain after 2 weeks of home treatment, if the knee becomes warm, or if you have fever along with a painful, swollen knee.

Some people with knee pain need more help. For instance, if you have bursitis, your doctor may need to draw out extra fluid from the bursa in your knee. If you have arthritis, you may need an occasional corticosteroid shot to settle down inflammation. And if you have a torn ligament or certain knee injuries, you may need surgery.

Overexercising Or Excessive Movements

Knee Pain

One of the primary causes of knee pain is stretching over ones limit and misusing the muscles repeatedly. This occurs due to continuous exercise that is too much to bear for the muscles. These effects are known as strains or sprains. They can be treated at home with minimal effort.

The area that is bruised, swollen or tender is to be identified and no amount of weight should be put on it. The first action is to stop the activity and take ample rest. It is beneficial to apply ice or wrapped vegetables for about 20 minutes in a periodic interval of 2 to 3 hours. Wrap the area with a bandage and keep it elevated for the swelling to ease down.

What Causes Patellofemoral Pain

It is probably due to a combination of different factors which increase the pressure between the kneecap and the lower part of the thighbone . This may happen during running, cycling, squatting and going up and down stairs. It is likely that the cause is not the same in everyone affected.

Situations where this can occur include:

  • Overuse of the knee, such as in certain sports – particularly at times of increased training.
  • Cycling when the saddle is too low or too far forward.
  • Some people may have a slight problem in the alignment of the patella where it moves over the lower femur. This may cause the patella to rub on, rather than glide over, the lower femur . It may be due to the way the knee has developed. Or, it may be due to an imbalance in the muscles around the knee and hip – for example, the large quadriceps muscle above the knee and the muscles that stop the hips from tilting when standing on one leg.
  • Weak hip muscles may cause patellofemoral pain by causing the thighbone to be slightly turned inwards, leading to the patella being pulled slightly to one side.
  • Foot problems may also play a part – for example, where the feet do not have strong arches . This makes the foot roll inwards , which means the knee has to compensate for the inward movement. However, it is unclear whether this causes the knee problems or may be caused by the knee problems.
  • Injury to the knee – including repeated small injuries or stresses due to sports, or due to slack ligaments .

Other Causes And Symptoms Of Knee Pain

Other injuries, syndromes, and mechanical problems may also cause knee pain. These include:

ACL Injury An ACL injury occurs when you tear your anterior cruciate ligament , which is one of the four ligaments that connect your shinbone to your thighbone. It’s a common injury among people who play sports like basketball and soccer, which require sudden changes in direction. Call your doctor immediately if you experience symptoms of an ACL injury, such as a loud pop or “popping” sensation in the knee, advises Mayo Clinic.

Fractures A knee fracture can occur if the knee bones, including the kneecap , break during incidents like falls or auto accidents. It can also be caused by something as slight as stepping the wrong way if your bones are weaker due to osteoporosis, per Mayo Clinic. Call your doctor right away if you experience symptoms of a knee fracture, which include sudden pain around the kneecap or in the knee itself, possibly with swelling inability to bend or straighten the knee or to hold the leg out straight deformed appearance of the knee or bone protruding from the skin of the knee, per Johns Hopkins.

Patellofemoral Pain Syndrome Patellofemoral pain syndrome, which is sometimes called runners knee, refers to pain between the kneecap and the thighbone, per Mayo Clinic. This condition is common in athletes and young adults, and can develop in older adults due to arthritis.

Mechanical Problems Several mechanical problems with the knee can also cause pain, including:

  • Medications: Your doctor may prescribe medications to help relieve pain in the back of the knee and swelling and treat underlying conditions like arthritis.
  • Physical therapy: Your doctor may prescribe stretching exercises or a physical therapy/rehabilitation program to help you restore range of motion, strength and stability to your knee.
  • Injections: In some situations, your doctor may suggest injecting medications and other substances directly into the knee joint in order to reduce inflammation, lubricate the knee and promote healing.
  • Surgery: If conservative measures do not provide relief, your doctor may recommend surgical options.

Possible Complications Of Surgery

What causes sharp pain behind knee? How can it be managed ...

The complication rate following total knee replacement is low. Serious complications, such as a knee joint infection, occur in fewer than 2% of patients. Major medical complications such as heart attack or stroke occur even less frequently. Chronic illnesses may increase the potential for complications. Although uncommon, when these complications occur, they can prolong or limit full recovery.

Discuss your concerns thoroughly with your orthopaedic surgeon prior to surgery.

Infection. Infection may occur in the wound or deep around the prosthesis. It may happen within days or weeks of your surgery. It may even occur years later. Minor infections in the wound area are generally treated with antibiotics. Major or deep infections may require more surgery and removal of the prosthesis. Any infection in your body can spread to your joint replacement.

Blood clots. Blood clots in the leg veins are one of the most common complications of knee replacement surgery. These clots can be life-threatening if they break free and travel to your lungs. Your orthopaedic surgeon will outline a prevention program, which may include periodic elevation of your legs, lower leg exercises to increase circulation, support stockings, and medication to thin your blood.

Blood clots may form in one of the deep veins of the body. While blood clots can occur in any deep vein, they most commonly form in the veins of the pelvis, calf, or thigh.

However, if you have sudden knee pain that turns into persistent pain, you should always see a doctor.

In the article below, we will talk about the causes of sudden knee pain to plan your next steps.

Knee Replacement Complications In Former Athletes

In a recent paper, doctors from NYU Langone Medical Center, Hospital for Joint Diseases suggest that total knee arthroplasty is often the best answer for end-stage, post-traumatic osteoarthritis after intra-articular and periarticular osteoarthritic fractures the knee.

However, total knee replacement in the setting of post-traumatic osteoarthritis is often considered more technically demanding surgery and the surgical outcomes are typically worse for these patients. The goal of the NYU paper was to create a new classification label for post-traumatic osteoarthritis patients and improve medical documentation and improve patient care.

  • The researchers looked at post-traumatic osteoarthritis patients who suffered from osteoarthritis as a result of high demand or athletic activity. These were on average were younger and healthier than the primary total knee replacement population .
  • The healthier post-traumatic total knee replacement group had the following complications:
  • higher rates of superficial surgical site infections,
  • bleeding requiring transfusion,
  • increased length of hospital stay,
  • and 30-day hospital readmission.

In a similar study, doctors at Duke University also recognized that Total Knee Arthroplasty as an important treatment for post-traumatic arthritis. However, these researchers also found complications that should not be expected in a mostly healthy patient population.

Ligament Tear Cartilage Damage And Dislocated Kneecap

During injuries that affect the knee, chances of injuring the cartilage, ligaments, tendons, and kneecap are high. The primary symptom of such injuries is the instability of the person to stand tall and erect. This is due to the pain, change in shape or direction of the associated muscles and bones. One could often feel a grinding sensation if there is damage to the cartilage along with other symptoms like knee lock, sounds, swelling, and worsening joint pain. In the case of dislocated knees, the patient will feel a popping sensation and will not be able to straighten the knee.

Ligament repairs are treated with the minimally invasive surgical procedure while cartilage damage can be treated at home with the help of painkillers and an ice pack. Remember to keep the leg elevated and not apply pressure. Severe cases can be dealt with through surgical procedures such as cartilage replacement, joint replacement, or procedures to enhance cartilage growth.

Treatment for a dislocated knee is a process known as the reduction in the absence of any fractures or ligament tear, where the doctor guides the bone to its right place. This is followed by X-ray checkups and physiotherapies. In the case of additional injuries, the patient will have to undergo surgery. Post-surgery, the individual will be prescribed the required painkillers and the leg has to be elevated and iced with intervals. Physiotherapy sessions will follow to attain recovery from a dislocated knee.

Possible Benefits Of Total Knee Replacement Surgery

Knee Pain? Here Are The Top 5 Causes

Regardless of whether a traditional total knee replacement or a minimally-invasive partial knee replacement is performed the goals and possible benefits are the same: relief of pain and restoration of function.

The large majority of total knee replacement patients experience substantial or complete relief of pain once they have recovered from the procedure. The large majority walk without a limp and most dont require a cane, even if they used one before the surgery. It is quite likely that you know someone with a knee replacement who walks so well that you dont know he even had surgery!

Frequently the stiffness from arthritis is also relieved by the surgery. Very often the distance one can walk will improve as well because of diminished pain and stiffness. The enjoyment of reasonable recreational activities such as golf, dancing, traveling, and swimming almost always improves following total knee replacement.
