I had the shingles last year...didn't make it to the doc on time so he couldn't give me anything to help the pain or the duration of the virus. I had to just wait it out. That sounds drastic, but do not dispair...even though it was painful it wasn't any worse than some things I've had to endure with fibro. Maybe I was one of the lucky ones...you might be, too. Everyone is different in how they fare with shingles.
Try to relax...get plenty of sleep and drink lots of fluids. Of course, I'm sure you know not to scratch the lessions. I didn't have lessions on my face...mine were on my right side on my torso. If the lessions go anywhere near your eye go to the doc! It sounds scary and might look scary but they will go away. Don't panic or get stressed as that will make them worse.
Take care and hope you will recover from this soon!
