Welcome to Healing Well :)
IBS can range from mild to chronic pain and symptoms. Upper pain could be the cause of gas which can really cause bad pain. If your back is hurting too, I would almost wonder if you are having problems with your gallbladder. There are much more people on here that can help you with that but it sounds similar to other's who have had bad gallbladders. Constipation can be excrutiating in terms of pain. I lived with it for many years and some days didn't think that I could live like that anymore. Took a long time to find the right thing to make my life better. If you have a strong feeling that more could be wrong with you, I would suggest maybe getting a second opinion from another GI doctor. I'm sure you'll get more responses.
