My Partner Is 80yrs Old And Has Parkinson's. He Has

My partner is 80yrs old and has Parkinson's. He has a catheter, often has constipation, and we have given mini enemas in the past. He has now a thin pale yellow liquid discharge dripping from the rectum with a clear mucous at the opening. He has not passed a stool for 2 days (nothing unusual) but feels he needs to.
