I had shingles before and I am just getting over my second bout. The first one was around my eye but this time I had it over my knee all the way to my foot. Now, I did not see very many blisters but now that its almost over, there are dark blotches all around my leg and foot. There is still a lot of pain all the way to my hip and syatic (do not know how to spell it). Why the dark blotches rather than red/pink ones. My Dr. does not recommend that I take the preventive shot because he feels that because I had it, this will prevent it to appear again.
