I have knee pain when going down stairs, sitting indian style, or straightening my leg when it has been bent for awhile. What could this be?

I have knee pain when going down stairs, sitting indian style, or straightening my leg when it has been bent for awhile.  What could this be?

OA vs PFPS: Two possibilities are most likely. The first is osteoarthritis, or wear and tear ("rust in the joint"). This is usually in middle-age people but can occur earlier with excessive use. Another option is patellofemoral pain syndrome, or inflammation where the kneecap tracks on the femur (upper leg bone). In most people, these can both be helped with antinflammatory meds and quad strengthening. ...Read more

Uncertain: Since it is one knee it could be a cartilge problem. You will need an evaluation by a knee specialist like a rheumatologist or orthopedic surgeon. If surgery is recommended get a 2nd opinion from a rheuamtologist.You will need imaging and maybe even an MRI ...Read more

Knee pain on/off 7 yrs. Around/behind kneecaps. Both legs, not always same time. Can’t link to weather, activity, temp. Heat=more discomfort. Akp?

therapy is importan: This sounds like you have patellofemoral pain syndrome. This is the result of mild damage to the cartilage behind her kneecap or a chronic strain to the muscles attaching into the kneecap. If symptoms of swelling, catching, locking and giving way occur he may require surgery. If these do not exist physical therapy stressing the core, hip muscles and the muscles would be indicated. ...Read more

See below:: I believe you have an urinary tract infection that you need to get treated; your knee problem sounds like a meniscal lesion or 2, causing all your knee/leg problems. You should see your doctor for the urinary infection and an orthopod for the knee problems. Good luck. ...Read more

Have sudden pain behind knee. Is that one of the signs and symptoms of leg blood clot?

Probably not: Sudden onset pain usually is associated with something like a muscle tear or cyst rupture if the pain is very localized to behind the knee, not involving the entire lower leg. However, any time there is concern about a possible blood clot, you should be checked by a health professional. ...Read more

Clinical more import: There is much more importance in this kind of situation of the clinical picture for the presence of a blood clot than the value of 1 single lab value. If your other testing is negative multiple times and a doctor's examination of the leg is negative for suspicion of a clot then, 1 single abnormal lab shouldn't change anything.

I have a venous us and see a vascular doc in a week for severe bilateral foot/ankle swelling attacks. The leg cramps/pain behind knee. ? How to sleep?

One of the concerns : Is a clot, a bakers cyst is another that comes to mind. A clot is serious if present and needs to be dealt with immediately. The question is did you already have he ultrasound or not? If you didnt go get it done...And do not wait a week. If you did and it was negative, i would call the doctors office anyway explain your ina lot of pain and ask to be seen earlier. Perhaps ice would help.... ...Read more

L5-S1 microdiscectomy Fri for left leg sciatic pain. Calf/foot pain relief w/some thigh/behind knee pain. Pain less AM but sharp pain down left leg into foot w/pain level of 9.5 & hurts sitting/lying.

Microdiskectomy: Give it some time; sometimes simply moving the roots around can upset the lumbar plexus and give you intermittent (even quite severe) pain, although it resolves within a week or two. Getting to the disk requires mobilization of the roots and inflammatory changes from that- or the disk herniation- itself can give this pain. As long as bowel and bladder OK, hopefully this will resolve also. Best! ...Read more
