... external. I never know when it will attack me , but when it attacks I get very sick, it effects my muscles, my joints, can't stay awake, I get a major headache. And I cannot go to work when I get this rash attack. What is it that is causing this rash? My eye socket hurt, the rash is very red and has raised bumps. And the odd part is it only last three days. The first day I am deathly sick the second day I am weak from the first day, rash clears up a bit then the third day gone!!!
