Its so soft tools mushy with raged edges , not bulk shaped stools. Sometimes it comes in thin shaped and soft. When it pass through I feel burning in anus. I sometime  take ofloxacin oridazole tabs for temporary stops this frequent visit to toilet. I feel cramp on the are under the left hand just below the rib cage, May be left side of stomach. When I something I do burp even if it was just water. What could be the problem with my body? Please help.
