HI, thanks for using healthcare magic
The fall backwards may not be linked to the
bloating and abdominal discomfort that you are experiencing.
If you are using NSAIDs to help with the pain or have any problems with
constipation due to pain in sitting then this may be a link.
Other causes would be:(1)reflux
(2)food intolerance
(3)celiac disease
(4)side effect of other medication
(5)use of gas producing foods such as carbonated drinks, cabbage, broccoli, cauliflower, brussel sprouts, beans, turnips
The use of reflux medications such as pepcid, zantac, nexium,
prilosec,
prevacid,
protonix.
Even if there are no obvious symptoms of reflux, these meds would help with bloating.
I hope this helps
