Hi, I was wondering if anyone could help me. I have been having severe back pain and abdominal pain (upper under my ribs) This has been happening since the begining of June with an odd day off inbetween. I ended up being admitted into hospital for 4 days with suspected Kidney Stones. This was ruled out after a CT Scan, but they are now saying it could be IBS. The pain is constant, dont really need to go to the toilet often or am really constipated. Im not 100% convinced its IBS. I get bloated and also am suffering with trapped wind. I was wondering if IBS pain is constant and does it affect your back and how severe is can be. Im getting pretty pee'd off now as its been 8 weeks and still in pain.any comments would be greatly appreciated.thanksNicky
