I am having a terrible flare for the past two months. I am getting rib/thorasic/groin pain.

I have a lymph node in my groin that is very swollen and tender. I feel like it is worse when my other inflamation subsides a bit. I have a few more nodes that are in the same area that are less big and tender, but still noticable.

I am obviously going to the Dr to make sure it is "nothing else",

but I am wondering if anyone else has experienced painful lymph nodes during a flare up. I have read that this is common in RA, but have not seen so much info about AS.

Any experiences/thoughts?

Thanks so much.
