Hi all iv been having a relatively quiet spell with my ibs lately thank goodness (touch wood) however i also have back problems and take 2 codeine 30/500mg a day on a good day and up to 8 on a very bad day of pain. Anyway on saturday my back went from me as it does sometimes and i had to up my pain meds to include 5mg diazepam twice a day. I held off taking antiinflzmmatries as they are my stomachs worst enemy but the back pain got so bad by sunday evening i had to take naproxen. I have taken a total of 5 naproxen tablets since then aswell as my diazepam and codeine and only today are things easing off but my belly has now started complainjng. Its a horrible gnawing ache on the upper right of my abdomen under my right breast which gets worse when im hungry altho eating doesnt completely get rid of it and wakes me up at 4am in the morning. Someone suggested it may be a spasm and to try gaviscon. Anyone else had this?
