Ab Muscle Cramps, anyone?

Has anyone experienced excessive ab muscle cramping? I mean, I get them if I sneeze 5 times in a row, or lean over to the side to pick something up and the only thing to get rid of it is REALLY stretching out my core... We're talking me putting my arms up into a door frame and arching to stretch out the muscle for 15 min. or so. if I stop too soon, I feel the cramp come back. I can get them in multiple places (not at once, thank God) which is weird as well.

I drink a TON of water/liquids (70-120 oz daily) and I take daily vitamins.

Any ideas?

Have you asked a doctor? I wonder if it is adhesions.

Its def not a hernia. is what he said and couldn't really tell me much. I will look up 'adhesions'
