Looking for suggestions regarding Shingles..

Ugh...we are supposed to be headed for our annual trip to a local CG with all the grandkids next week. It is something we do every year and the kids just love it. Unfortunately last Thursday I felt a familiar pain developing under my arm and unfortunately was apparently getting a recurrence of shingles!!!! Of course this was all developing over the 4th of July weekend and so I couldn't get into my doctors office until Tuesday, which was long past the 72 hour recommended for starting Valtrax. Needless to say, I am not a happy camper at the moment! Does anyone have any suggestions to help with pain/blisters? So far the blistered area is only about 1-1/2 inches long but but is getting longer and redder by the day. The pain encompasses a much larger area...any suggestions would be appreciated. Thanks! I am praying that this starts to diminish by time we leave for our trip next week!
