Hi, For the last week I have felt quite sick, dizzy, hot and cold sweats, feeling like i need to throw up, headaches, being really shakey. I went to the doctor and they said I had a virus. But this morning I blew my nose and charcoal black mucus came out and i stuck the tissue up my nose and it came out black. I read online that this could be a problem and was wondering if these could be connected as im still feeling all of the symtoms said before or is it just a coincidence?
