Had similar experience. Had allergic reaction to penicillin first prescription, which triggered my full body to come out in itchy hives. Went through 3 courses of different antibiotics until I was fit enough to get out of bed. Had bad guts for a couple of years following, which was usually an alternation between diarrhea and constipation. Sometimes I&#x27;d sit on the throne several times a day and no movement, except mucus or eventually, blood, as I&#x27;d developed piles.<p>I went on a super high fibre diet, ate as much low calorie food as I could a day to keep things moving. Ate lots of fermented foods, mainly dairy, sauerkraut, cured meats. Eliminated sugar, took up cycling to work to get fit. I&#x27;ve not been ill since, my bowels are moving, and piles are gone. Not the most pleasant story, but thought I&#x27;d share it.
