I have burning, tingling & piercing rash on the back of both of my thighs, approx mid line, I also have had tingling numbness on my right outer thigh in front that radiates to where the rash is, the tingling/numbing sensation started 3-4 days prior to the rash appearing. I had shingles 7 years ago (text book, on my mid back to right side). I m thinking I have shingles again??
