I am a 46yr old Mother of 3. For the last 8 months I have been feeling very ill, extreme sweating, nausea, diarrhea, gas and horrible cramps. The right side of my stomach gets really bloated and hard.  It knocks me down for days and then I start. I have also been having them every 2 weeks. They last 7 to 8 days each time. Does anyone do this? Could it be a cyst?
