Smell of sulfur when I fart, and bleed
I have a very strange question that's been bugging me for a while, and Googling is really hard (I've found) to get an answer to this question:
I itch quite a bit analy (which isn't really the question or topic). I've had the itch for about ten years, and I know why, as I've had periods where I don't, so it just bubbles down to my own scattered brain to keep the routine I need to avoid it.
HOWEVER: Whenever I've scratched or dried so that I (externally) bleed, whenever I fart, the farts ALWAYS smells like sulfur (burnt). Is there anyone who can help me with a scientific explanation to the specific smell occuring in these situations? It really boggles me, and I find it hard to belie that it's just a random combination or blood and methane causing a smell identical to sulfur..
