I was having issues with swollen lymph node in groin area. Surgeon removed it everything tested ok. Now I have rash again on upper thighs. I'm still having issues with joint pains and overall body hurting. I have a thyroid issues already. I told my Endocrinologist about the joint swelling and body aches. She did a bone density test, everything came out good. I don't know where to turn with these issues. Everything I read regarding the rash, elbow swelling and joint pain possibly relates to arthritis? And thoughts would be greatly appreciated.
