Good evening sir. You seem to be having irritable bowel syndrome
.Since you have already taken antibiotics for 7 days, possibility of infection is less likely. It is mainly a disturbance of the bowel where one person can have either constipation
which can persist for long. You need to consult your gastroenterologist once. Among st the other remedies, you need to include high fiber diet( or you can take artificially from outisde as it will help to form bulk of the stools, something like Isabgol. Get proper 8 hours of sleep and reduce your level of stress
. All these are aggravating factors. I can write a prescription but i ll recommend you consult your doctor once, so they can examine you before prescribing medication.Hope the information was useful.
