Almost 2 weeks without pain now, and am virtually back to normal. I had my doubts when my doctor prescribed amitriptyline, but it is either working or it's a coincidence that starting to take it happened at the same time as starting to feel better.
As of yesterday I stopped getting in the shower as an alternative to wiping, which is a huge thing for me! I don't have to sit in a bath after every BM and am not dreading each BM any more.
I'm still taking all the supplements I was before, and something to help counteract constipation that amitriptyline can cause, and probably will for a long time as I'm not 100% sure what has been responsible for the improvements.
Bottom line (excuse the pun) is that I feel good! It feels great to be getting my life back, and am hoping this is the end of it. Keeping my fingers crossed.
I just wanted to thank everyone on here who have helped me in my lowest moments and hope that you all feel better soon.
