Could this be shingles? Doctors are at a loss here!?

Sounds like shingles. The key clue is the series of red rashes with small blisters. It's important to treat shingles within the first 72 hours of the outbreak. Shingles, left untreated, can be serious, and can cause blindness if it travels to the nerves in your eyes. Standard treatment includes taking antiviral pills and using antiviral creams such as acyclovir. After wards,you may find that Vitamin D can help with the lingering nerve pain from shingles called neuropathy.
