I also have IBS
, and have just recently been diagnosed with AS(Ankylosing Spondylitis), which is a rheumatoid arthritis disease, affecting the spine, and joints,
and have been taking Non Steroid Anti-inflammatories.
I am 33, and had some sort of attack yesterday, severe abdominal
pain, not able to stand, lay or breathe properly. I have had that type of pain before, but never this bad. It did pass after about 30 mins or so, but is still tender today.
