Red, itchy, chickenpox-like bumps for over six weeks?

HELP! I'm so tired of this. I've had these horrible itchy red bumps for 6 weeks now. They look a lot like chicken pox, but they have been here almost 7 weeks. I've had a low grade fever the entire time and stayed sick, too with mostly upper respiratory irritation and sore throat. I've been to 6 different doctors, including an infectious disease specialist and no one has a clue what is wrong!!! The last doc (the inf. disease specialist) ran a full panel of bloodwork, but the results are not due to come back till about Thursday of this week, and he isn't even sure the bloodwork will show anything. I need some answers and some relief! Has anyone ever dealt with something like this?
