I have had three partial blockages and all three sent me to the ER. I'm my case I had no bowel sounds, no bowel movements, I threw up and was in so much pain I couldn't take it. I know exactly what I ate that blocked me...popcorn, raw baby carrots and hazelnuts. I now avoid those three things. When I was blocked or partially blocked I knew it. There was no doubting what it could be, but that's me. I've had other episodes where I have waves of pain that come and go, but I've been able to get through them. I did the liquid diet for a few days to calm everything down and I put a heating pad on my tummy. That helped me relax and eventually things made there way through. It wasn't fun, but I knew I could survive it and it would eventually pass.
I hope you're insurance kicks in soon and you can get some relief. I have xanax that I take occationally to help me relax because it seems like the pain makes me tense and the tension causes the pain to get worse, so if I can break that cycle I can start feeling better. Good luck and I hope you feel better.
