I’ve had diahrea so my mum gave me a co

Patient: I’ve had diahrea so my mum gave me a co codamal tablet, I took about 3 in 2 and a half days! It’s been 34 hours since I last took one and I’m struggling to pass stool. It feels like I need to go to the toilet when I sit down for a while and when I go I only pass a little bit of soft stool whilst it feels like there is loads still to come out. I’ve been doing this 2 times an hour for the past day and a half why can’t I pass stool fully?

Doctor:
