Hi @Davesey27.....Yes, ME/CFS can definitely cause problems, since most of us have IBS anyway. That can come in waves ranging from what you're going through to the opposite. Also, I had a bowel blockage last summer and had to be operated on to relieve it. I had none of the usual symptoms of needing it, just felt like I had a bad stomach flu and almost waited too long before having it checked out. I was sent immediately to the hospital.
Colace is another good stool softener and Miralax is good for moving things along...it's not habit forming, dissolves easily and is light years better than the likes of Metamucil, etc. Digestive problems have been my constant companion for 35 yrs. or more. A pain, aren't they? I wish you well....Yours, Lenora.
