E.,
First, was a blood test done? And it was positive?
I lived in Phoenix, AZ at one time and came down with Valley Fever the first year I lived there. I was miserable. Every single day for about 2 months, my body would feel 'on fire' as the virus migrated through out my body.
Because it is a virus, antibiotics will not help it at all. The doctor who prescribed that was trying to be sympathetic and help you think he was helping. It's called the placebo effect.
Your husband must rest and sleep more than usual. He absolutely must eat right and do gentle exercise like walking, swimming, yoga and nothing too strenuous. He must wait this out and while he's waiting it out he should boost his immune system with fresh fruits, veggies, green powdered supplements from wherever you choose.
There is no cure for this virus. One's immune system and body must fight it off itself. The motrin will alleviate the achiness.
Also, for the red bumps, try the Psorian product, it has coal in it and it seemed to do the trick for me. The coal helps pull toxins out of the body.
I don't think going to another doctor is going to resolve this. I would only go again if something more serious than red bumps appeared.
Another option is to go a chiropractor for immune boosting treatments.
GL!
