I have a large lump on my upper inner thigh, close to the groin area. It is about 5inches long, about 3 inches wide and feels like at least 2 inches deep. I found it about 2 days ago. it has become very painfull. I have an Appt to see my Dr. in about 3 days. but i have started carrying a high fever for the last 2 days. Also, suffer from reacurring acute Pancreatitis. (non-alcohol related). could this high fever cause an Pancreatitis flair up. It kinda feels like I getting one. Any advise please.
