I took a ercefuryl tablet 200mg because I had a bit of diarrhoea,but now I can t pass any stools only slime and a little blood, which I feel like I need to go every 30 minutes or so could it be the tablet which I took yesterday, I have stomach ace. I would normally have a bowel movement 1 or 2 times daily, but have not had a proper movement for 2 days, I also have a headache
