Shingles rash has lasted for three months. Started as blisters on my neck. Spread to face, head, shoulder, chest, and now are small bumps - some red - in the same areas. Very itchy! Hard to sleep at night. Any thoughts? Is this normal? The doctor has me checking in with her via phone every week, but not seeing her. Keeps ordering medicine. Nothing helps much unless I take so much that it is hard to keep focused at work. Thanks for any help.
