Hi I've Had This Prob For About 3yrs I Got

Hi I've had this prob for about 3yrs I got drunk one night and I had to go to the bathroom and I force it out and there was a lot of blood in the toilet this was the first time. Ever now I've been having probes going to the bath room like hurting and burning and it feels like my skin is raring and blood sometimes on the outside of my stool
