Maltracking: The knee cap (patella) rides in a channel at the bottom of the femur (patellar femoral groove) while being held in place by the patellar tendon. Sometimes it will slip and ride along one side of the groove, lose cartilage, and become painful. There are surgeries to correct this, and braces that can stabilize. See your orthopedist for an eval. ...Read more

Knee Pain: Pain in front of the knee is very common and is called Patella Femoral Pain Syndrome. Many times this can be treated conservatively with therapy, NSAIDS, and a cortisone injection. See an Orthopaedic surgeon for X-rays and an examination to make sure this is the correct diagnosis. Take care. Hope this helps. Joe Wilson. ...Read more

I feel a stabing pain just below the knee cap at the outer side while walking, is it related to oa. Thank's?

No way to tell: Without seeing you and examining your knee there is no way to make that determination, but the stabbing pain in that area is very atypical of what might be expected if this were due to osteoarthritis. See an orthopedist and have this evaluated. Good luck. ...Read more

MRI then surgery: With that many dislocations, surgery will probably be necessary to achieve stability of your patella. An MRI can demonstrate various areas of damage and guide one as to the cause of your pain. Bone bruising and cartilage injury commonly occurs after a dislocation. Time to see an orthopedist. A quality brace can give you some pain relief and stability. ...Read more

My knee has a burning stabbing pain that starts in back and wraps to right below kneecap also swells clicks and gives out? What is it

My knee has a burning stabbing pain that starts in back and wraps to right below kneecap also swells clicks and gives out? What is it

See knee specialist: Based on that limited description I'd consider ACL tear (instability), meniscal or cartilage injury (clicking swelling), and saphenous neuritis (burning pain wrapping from side of knee to below kneecap), but what you really need is a thorough evaluation by a knee/sports med expert who can actually examine your knee, determine if further testing (MRI, etc) is needed. Hope that helps. Good luck ...Read more

I have a stabbing pain on my Right upper leg on outside about 150mm above the knee. It come and goes?

Many possibilities: If there is no swelling, mass, redness or lesion involved, likely muscle spasm or pulled muscle of a small group of muscles. Pain will come on when spasm happens or when certain movements use the particular group of muscles.
Otherwise, need to rule out abscess, bone spurt, swelling, blood clots.... ...Read more

I occaisonally get one knife like stabbing pain in the same spot of the head. It knocks me to my knees and and my whole body will feel numb and tingly?

Paroxysmal hemicrani: Is thought to be a variant of cluster headache because of similar autonomic features. Both cluster and paroxysmal hemicrania are classified as trigeminal autonomic cephalgias in the new IHS classification. However, almost all cases of paroxysmal hemicrania are relieved by Indomethacin and this response is considered diagnostic for paroxysmal hemicrania.
