A few months ago my mum had contraction pains. Went on for quite a few hours every time a "contraction" hit she would have to stand up and bend over holding onto the arm of the couch. She had to breathe through them too ! She said it was just like being in labour. Pains tapered off enough for her to go to bed. It was horrible to watch and I was ready to take her to the hospital ! Not sure what it was but we assume it was bowel related...

Glad you are feeling better ! Probably worth getting checked out - especially if it happens again !
