postherpetic neuralgia
"I got shingles on my scalp left side forehead and eye.  I was in hospital for 5 days on an IV for both antivirus and antibiotics.  The doctor had said that it was the worse shingles he had seen. After the scabs had gone I was Prescribed lyrica.   I take 300mg at night and 25mg in the morning.  It has been 5 weeks since I developed shingles and my face and scalp are still numb.  I have intermittent pain shocks.  I believe the lyrica is effective as I can't imagine what it would be like if I didn't take it.  I'm not sure how long I am suppose to take this but I imagine by other feedbacks that it could be months."
