I have emergency surgery about seven weeks ago for a ruptured appendix, spending five days in the hospital, three weeks off work...I have recently, off and on within the last two weeks, been experienceing stomach cramping, opverall pain, bloating, and some nausea, especially within a half hour or eating of drinking...could this be related? Could I have developed a sensitivity to foods all of a sudden, or should I be concerned about something else...it almost feels similar to some of the initial cramping I felt the first day I went into the ER, to be sent home, misdiagnosed, with a UTI....
