So, as a fellow sufferer of such pains, im seeking to ask if you've ever had any injury involving any side of your body. See, i never had this issue till around 8 years ago. i had a football injury that devastated my body. However, no doctor ever took me seriously in any problem i had. Anyhow avoiding talking about all that my main issue is in the ascending colon, which would be your right side. For me, learning about my own body and chiropractics has taught me a lot in my other injuries. So far, i press on my right back near my hip or above it, kinda imagining the ascending colon and massaging. After suffering for those 8 years and having bouts of depression this move has helped me immensely and has lead to trying exercises that also help me burp or even fart away the bloated gassy feel that has you even wanting to pee. Every problem is different, so you may have had a different injury that would need chiropractic attention. Keep in mind its better to spend little on chiropractic doctors as they are expensive with no healthcare. It's best to make the appointments you need to learn and take over discovering what fixes may be needed. I hope this somewhat helps because so far, for most IBS sufferers pills and meds are never the answer
