Welcome to FM! If there is one thing that I have learned, that is that this disease is completely odd and crazy. I feel like I have had it all. When I was in high school I had a gland that swelled up behind my right ear and it really hurt. My mother told me to get over it. Later in life I had these little glands swell in my labia. They were the size of an eraser on tom of a pencil.

Yes below at the back of knees are swollen and painful.. And in my thighs and groin it's burning as I am typing this. Very painful and leg starts to swell

I have been personally experiencing that same thing in my groin for the past 4-5 years, but it comes and it goes. Recently it became worse in the past month were the pain was becoming unbearable to even walk. The doctors were not sure why, so they decided ti do a biopsy just to be sure everything was fine. Thank GOD it was!!! Doctor said it was just inflammation so it may be another symptom of the condition but again this I am not sure for certain since everyone's experience is different. I recommend going to your doctors if its not better in the next few days.

I understand , I also have severe swelling behind my knees, plus my legs swelling.. 8 started drinking more water and it has helped..No cure but I hope it I of some help..Take care gentle hugs, Shirlie
