I've been put on a course of 8 (or maybe 10, can't remember) weeks of using GTN on my anus to try and heal my AF. Not having done this before, I'd like some advice:
Where should I apply the GTN - all over the anus or just at the 6 o'clock location where my AF is?
How much should I apply? I've read the headaches are pretty bad, so should I just use a pea-sized ball of the stuff?
How often should I apply it? Twice a day? After a BM, or just at any time?
How far should I stick it up the canal? Should I just apply it externally, or should any go inside?
