Hello,

I’m a healthy 21 year-old woman overall, but I suffer from PCOS, insulin resistance and palindromic rheumatism (a form of rheumatoid arthritis that doesn’t damages the joints). Recently I’ve also been diagnosed with a pinched nerve at L4/L5/S1, after I complained of moderate to severe calf pain as well as numbness to my doctor. An MRI was done which confirmed the diagnosis. I started PT and after three months got a lot better and stopped.

But recently I’ve been having intermittent aches behind my knees and a vague cramping pain in my calf. The calf pain is similar to I’ve had before, so I’m not worried, but the pain behind the knee is a first.

I went to see my doc, who a priori ruled out a blood clot, as my leg is not swollen, red or warm; the pain is not severe or constant and moves around a bit (behind the knee, sometimes above it into the tight, sometimes around it…); and I’ve no risk factors. I also sometimes get pain in my buttocks.

Could this pain behind my knee be caused by sciatica?
