Hi, Welcome to Health care magic forum.
As you describe, it appears to be the flatulence
, that is causing feeling of some thing passing in side.
The reasons may be the infection of the intestines, indigestion
I usually prescribe to my patient with such symptoms omeprazole
, ofloxacin, ornidazole
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have good health and resistance against infections.
Wishing for a quick and complete recovery. Thank you.
