I do not believe It is relative to the tbol. Id go back to normal dose and give it a little more time. I had a similar rash a while ago. Not sure what's its called. If its the same type of rash, you should expect the spots to become dried out in a week at 2.
Like I said, sounds very much the same. Looks like ringworm, but does not it, and spreads. Not majorly, but yeah.
