Have been diagnosed w/ autoimmune disease & fibromyalgia have large non painful swelling in groin/thigh junction which has been getting larger ?

Inguinal hernia: The hernia by itself isn't a dangerous condition. It doesn't get better or go away on its own. However, if untreated it can lead to a serious complications. If hernia is enlarging or getting painful the surgery is warranted. Rec.: see your pcp for diagnosis and referral. Good luck.

Autoimmune/Pain : This is quite complicated. I treat these conditions in my office quite frequently. What I have learned is that the traditional medical methods to treat these conditions have failed miserably. What you have is a combo of hormonal imbalance, inflammation, and food induced auto immune disease. In my practice, 95% patients improve or have their sx's resolve using this approach.
