My husband has been diagnosed with gall stone recently and it was identified after he had a gall pain attack..The dr had prescribed medications to prevent infection if any for liver or gall bladder. He is yet to start the medicine but today he had a bowel movement and along with it he got couple drops of blood..Bright red in colour and also he had been a bit constipated for past few days. Should we be concerned? We are looking at surgery but not immediately due to covid situation. Any advice is helpful
