Digestion and stomach problem.

Hi, my digestion is poor, motion 1's for 2 days.3 months before while pooping I felt something is stuck at my anus, like a small bone piece of chicken. I feel it rarely, I went to gym from Nov to April 5 1/2 months by maintaining strict diet to loose weight, after I tested +ve I stopped diet,  uncontinued because of lockdown,there was dry cough and slight pressure at my chest,thought again I may infected with covid, had CT scan but there's nothing, Consulted doctor she suggested only 2 caps maxbenfit daily1 & Protera D before food 1 morning, after 3 days I felt that something is growing inside my anal, stuckynes while pooping, by YouTube&friends suggestion started taking more water and curd. but Tue morning I suffered with stomach pain and took Protera d had breakfast, vomited it, little nausea taking pills oflex and for vomit, now my stomach is delicate, understood that it is a gas and digestive problem, morning also felt nausea because of gas.2 much urine, no motion suggestions!!
