i have an abdominal right at the center of the abdomen , most of the times the pain is relievd by either defaecating or gas expulsion. Sometimes its not relievd even after all this, and then i drink something very cold, then seems to be better, but after 2 mins, back again!! after some time it spreads to the lower abdomen, more to the right, just below the umbilical line.. its really very painful. I have had it since 2002.. help!!
