I am having severe stomach bloating, noises, nausea, for the last 3 weeks. and i was standing up, pulling my workout pants off and something internal , on my left side, deep, twisted and it was pressure and sticking out. i stood up and pushed on the long bump. it flipped back and went down. no sharppain , only pressure. what could this be? i have had a c section 28 years ago. no problems like this before
