@electracat I too suffer from constipation. In my younger years diarrhea was my problem but after stage IV cancer treatments and eating more protein the table turned.
It sounds like you’re having a tougher time than I am for sure. You’re obviously pushing way too hard but I know it’s hard not to when you’re in pain.
I hope you find the answer! I take Metamucil (when I remember) and that seems to help.
Wishing you the best,
Jody

@electracat it might be a good thing to keep a diary of your BP a couple times a day..make sure it isn’t high. Extra one after the nose bleed starts. Take for a week or so. Then talk with your Gastro about it!
