I have been having attacks for probably a year and a half, suddenly with no warning, I have extreme pain in the lower abdomin. The strange thing is that it seems to relieve the pain if I burp and keep doing that for sometimes a half hour until the pain stops. I usually feel sore in that area for a day or two as well after an attack. While the pain is going on, I sweat and go into a fetal position, by the time the pain has subsided I am very tired. Someone please help, anyone else have this? What do I do?
