i have had a pain under the right side of my ribcage for a couple of months now, accompanied by on off diarrhea which is worse in the mornings. I also had lower back pain for a while which now seems to hve eased off but instead i have had headaches for the last week. i went travelling around asia a few months ago and have been feeling ill since i returned home, i did have 2 bouts of food poisoning while i was away. i was prescribed omeprazole which i am currently taking, but the pain seems to be worse. any ideas? thanks
