I have been having really sharp pains in my right thigh, it feels like I am being jabbed with a knife. It only lasts a second or two each time, and happens a few times a day, but it is so painful that I yelp in surprise when I feel it. I thought it was nerve damage but I had an EMCG done at the Mayo in February and it was negative. I was wondering if swollen lymph nodes in the groin could cause this type of pain? I've recently been seeing a sarcoid doc at Hopkins (not officially diagnosed but will have a PET scan next week). Thanks!
