Welcome to the forum.
I am sorry your husband is having these problems and it is unfortunate, to say the least, that his doctors do not seem to have a clue about rashes.
It appears that your husband is on Incivek (since his doctors said the rash did not look like an Incivek rash). First of all, it may be from the Incivek but it could also be from Ribavirin. Second, the rashes from these meds take on all sorts of forms and shapes and characteristics. Whether the rash looks like their idea of what an Incivek rash should look like or not, they still need to treat it. It is a rash and it is a problem. In addition, these rashes from these meds, whether from Incivek or from Ribavirin, tend to spiral out of control rapidly. He needs treatment for that rash NOW. If the nurse set up a Dermatology appt, that appt. should be today, or tomorrow at the latest. This appt. should be on an urgent/emergent basis. The rash from these meds is nothing to fool around with. The rash can (and has, in some people) jeopardized treatment. Some people have had to stop due to severe rash. Others have had to stop because their doctors did not take the rash seriously and the rash spiraled out of control. In addition, the rash is very painful and the itching will drive a person nuts. So the rash needs to be addressed immediately. If the Derm appt. is next week, call back and tell them that he needs to be seen today or tomorrow at the latest.
I had bad rash that my treating team also had no clue what to do. Over the counter medications are totally useless for these rashes when they are more than just a few bumps here and there. After much insistence and a lot of needless suffering and misery, I finally got on some meds that worked for it. Here is what I was prescribed, all prescription meds.
1) Hydroxyzone 50 mg every 6 hours as needed (the rash never got under control until I was using this medication every 6 hours)
2) Fluocinonide ointment for the body
3) Clobetesol solution for the scalp
4) Hydrocortizone Valerate for the face
I cannot stress enough that this rash needs to be treated aggressively and brought under control immediately. His treatment is at stake.
Just to let you know that the rash can take on many forms, I had the following: Rash ….. red skin, hives, wheals, confluent hives, macules, papules, pinpoint lesions, flat red-purple lesions, bright red lesions, dry scaling lesions, skin cracks/fissures (palms, fingers, knuckles), eczematous lesions, psoriasis type lesions; Itching continuous/widespread; Mouth and Nose Sores; also some weeping of the rash areas
Mine never got pus. That would concern me even more. Is it pus or is it clear fluid? I can see that either could occur because the the rash, itself, can have vesicles. Plus, any rash, especially if scratched, can become infected.
Here are a couple of links to some rash photos that some members posted. Click on the photo sections and look at all of the photos:

And here is a link to Incivek management. Scroll down (a little more than half way down) and you will see photos of their rash stages, although I think they tend to be VERY conservative in their treatment of it. They do not recommend treating it as aggressively as I feel it should be treated. That may be because they are trying to downplay it a little for fear of scaring people off.

Things that can help (in addition to the prescription meds):
wear loose lightweight cotton clothing, nothing heavy or thick seamed
wear as few clothes as possible (shorts instead of long pants, etc.)
keep the house cool (mine was at 66-68)
use very soft all cotton sheets on the bed
use a fan at night to keep cool (as well as air conditioning)
do not wear anything that picks (neck tags, lace, picky fabric)
avoid sox when possible (they will make the feet hot and they will pick)
cool showers
use hypoallergenic products (soaps, laundry soap, deodorant, etc.)
avoid the sun
avoid heat
There probably more that I forgot.
By the way, where is your husband in terms of treatment. Which week.
Best of luck.
