Yea defiantly anxious and stressed!! Could that be it??
You should learn how to describe your problems because symptoms need to be clearly link in time, anatomically, etc to get an idea of what the problem is. If your doctors are concern, they should get a biopsy of your ras. Could you be anxious?
That sounds like a lot of tiny things that you have pasted together mentally. Which makes them all worse.
As for the smell? No idea personally, aside from "injuries smell weird." One time, a rat bit me and the wound smelled like oranges.
