I am female, 30y. There is an itch inside my left knee, inside the joint, not on the skin, and only in the left knee. It occurs mostly night, but also sometimes during the day when I sit or relax. It only goes away for a while when I overstrech my knee to the point where it hurts and it s driving me insane. Sometimes I have it for sevral days, sometimes not at all for weeks, and it seems to get worse when my leg feels warm. Might this be restles leg syndrome?
Hi, I had gone through your question and understand your concerns. Restless legs syn Chat Doctor.  Another possible conditions should be considered too, as knee inflammation, arthritis, nerve damage etc. and It's hard to tell without further examination of your knee. I suggest you to discuss your concerns with your primary care Doctor. Hope this helped. If you have further questions feel free to ask.
