question: hello recently I have began working out again and I have been experiencing what I can only explain as charley horses in my stomach. the pain is escruiating. I happens during situps and anytime my stomach contracts often even during intimate moments. However the spasm I felt last night was the worst I have felt it started on the lower sided of lower abdomen and soon was the entire stomach. I was balled over in pain couldn t move and just started to breathe. It took five minutes to subside
