I am in the Post herpectic neuralgia phase of my second case of shingles. My doctor recently added steroids and valium to my already long list of meds (neurontin-which works SO good), lortab, lasix, potassium, ) and today i am feeling some relief. I experience the sharp, electric type "jabs" that almost bring me to my knees and the burning itching sking where the rash was is so miserable. I have to wear dresses all the time because any material next to my skin makes the pain unbearable. I asked about the shingles vaccine, but was told by my doctor that he didn't think it would really help me as i seem to have a predispositon for shingles. I would like to know what brings on the shingles rash! stress???? nerves?????? what???????
