I was diagnosed with reactive arthritis a month back and have been taking NSAIDs for its treatment. Initially it was alright but with regular use the medicine made me all gassy. I have been bloated for a week, burning feeling in the stomach with back pain and pain in the middle of the chest that comes and goes. Difficultly sleeping at night because of the constant urge to burp. I took Pan-d initially for three days but it did not improve my condition. What can I do to get rid of this gas completely? I stopped my meds for my arthritis currently.
