Try taking vitamin D 2000 IU.
Hi magiccastles92.
Sorry for what you're going through, but be patient and hopefully it will resolve soon, as you are young and health-conscious.
Most of your suffering and symptoms seem to be related to shingles,
however, instead of going to the ER, call your treating doctor's office first,
unless your condition is critical and your symptoms are dramatically taking
a turn for the worse.
Best wishes for a speedy recovery.
