Pain in abdomen near belly button.

Dear doctors, Would require your help to understand my problem. I had very light pain in lower abdomen exactly right side of belly button on 29th August 2020. I consulted online doctor, he suggested me to get the Ultrasound done to rule out appendix. After going through my ULTRASOUND OF ABDOMEN AND PELVIS report doctor suggested for ciplox-tz with probiotics. This worked for a week till the time I took medicine. Now the pain started again after 15 days i can feel the pain moving around the whole abdomen. Motion is semi solid colour texture is yellow. While eating or drinking anything either water or anything BURP are coming too much. I am not feeling gas passing.only burp is coming. Even from last 15 days I am not taking any very hard diet completely on boiled food. Pain is continuous like ant bite towards right abdomen more near to belly button Awaiting your analysis on the same doctor's. Regards Abhishek
