I noticed a rash last sunday on my back. The doctor thought it was shingles and did a culture. The culture does not show shingles. That rash has gotten somewhat better after a round of anti-viral, prednisone and gabapentin. Now the bumps seem to be appearing on the back of my next. Like Large mosquito bites. They do not ooze or get bliters. What could I possibly need to be checked for. I have had hives before and they don t look like hives either.
