hello...i am female, will be 60 years of age in April and in good shape. Anyway, I was at the gym tonight...doing fairly easy ab exercises when my right lower abdomen (inside) went into a severe spasm....felt like a living organism got caught inside my skin and was trying to get out...did not hurt...just could not move. my primary concern with this is that I had a colonoscopy (2012) that went wrong and ended up in picu for five days and 12 of my lower intestine removed. surgeon repaired me well, i am not on a bag....however, could this be part of the spasm proble,.. i have had two other spasms,within the last couple of monts (was not excercising) but not as bad as this evening. i think i need to see my doctor, however, if i don t have to go,...other than this, i am in excellent health and take no meds.
