I have been bothered with piles on and off for years and a couple of weeks ago I had a thrombosed one which needed lanced - it took 4 goes to get it shrunk. I've gone past the point of embarassment with my GP, I'd show my butt to a trained monkey if I thought it would help. Anyway, I run most days and am wondering if that is exascerbating the problem. I eat well and am not prone to constipation. Will I have to put away my trainers for a while???
