Causes Of Sudden Knee Pain Without Injury

Osteoarthritis; Sudden knee pain may be the onset of spinal cord injury, joint degenerative disease and a form of arthritis.

Osteoarthritis is caused by a number of factors, including injury, misuse and inactivity.

Arthritis of the disease; Arthritis exists in many forms, and some types, such as dementia, are autoimmune conditions. Psoriatic hemorrhage affects the skin and joints, especially the knee. The condition causes the bodys immune system to invade healthy tissues, causing inflammation, pain, and damage to the joints. According to the Cleveland Clinic, arthritis in the knee causes pain, tenderness, swelling, stiffness or slow motion, and silver or gray patches of skin or itching, red spots appearing on the skin.

Infectious arthritis; Also called blood arthritis, it comes on suddenly and can completely damage joints, according to the Arthritis Foundation. It usually attacks one joint, usually the knee. Bacteria, like staph, cause many cases of infection, joint infections, or fluid that circulates together. But some cases may be viral or fungal. Infections can be transmitted after surgery or through an open wound. Swelling, pain, fever and chills are signs of arthritis.

Risk Factors That Contribute To Acute Arthritis And Related Diseases

Several risk factors can increase your likelihood of having acute arthritis. Some of these risk factors are out of your control. Others can be controlled with lifestyle modifications.

In some cases, having one form of arthritis increases your likelihood of developing acute arthritis. A common example is rheumatoid arthritis and other disorders causing chronic joint damage. These diseases significantly increase one’s risk of infectious arthritis, particularly bacterial arthritis.

Other risk factors include:

  • History of joint infection or joint surgery
  • Injection drug use
  • Skin infections
  • Risk factors associated with sexual disease transmission

Medications And Steroid Injections

  • Corticosteroids. The most effective type of medicine for knee arthritis, triamcinolone acetonide , is the only FDA-approved medication to treat osteoarthritis of the knee. This is a corticosteroid injected into your knee that releases medicine slowly over a 3-month period. The slow release of the medicine has been found to relieve pain and swelling and reduce some of the negative side effects of steroids, such as increased blood sugar.
  • Topical pain relievers. The Arthritis Foundation recommends that people who have knee arthritis try topical pain relievers which is medicine you apply directly on the skin, instead of taking by mouth because it can help relieve pain without as many side effects.
  • Hyaluronic acid injection. Although more research on this remedy for knee arthritis is needed, it has often been used to help supplement fluids in the knee joint to decrease pain.

How Is A Pinched Nerve In The Knee Diagnosed

Your doctor will take your medical history and perform an exam to try to make a diagnosis and determine the cause.

The nerve in your knee can be felt as it travels around the top of your tibia, so your doctor may tap on it. If you feel a shooting pain down your leg, you probably have a pinched peroneal nerve.

Tests your doctor may order include:

  • Knee X-ray: shows any bone fractures or masses
  • Knee MRI: can confirm the diagnosis and show masses within the nerve and details of fractures of other problems in your bones
  • Electromyogram : tests electrical activity in your muscles
  • Nerve conduction test: tests the speed of signals in the nerve

The problem or activity thats causing the pinched nerve should be treated or corrected first.

Treatment is aimed at reducing pain and improving mobility.

Over-the-counter pain medication

Any medication that reduces inflammation can improve your symptoms, such as anti-inflammatories like ibuprofen and naproxen.

Heat or ice

Applying either heat or ice for 15 to 20 minutes at a time can give some relief from the symptoms.

If youve lost sensation, you have to be careful you dont get frostbite or a burn on your skin. An ice pack can make your symptoms worse if it puts too much pressure on the nerve.

Corticosteroid injection
