Have you had chickenpox before? If not then you do not have Shingles. If you have then I would recommend that you go see a doctor as soon as you can, they will put you on an anti-viral medication (I think the last time I had it they put me on fam-vir [however it is spelled]). I have had it a few times, it is (from how the doctor explained it to me years ago) the chickenpox virus stays in your body and never really goes away and Shingles is a form of it, and it is usually triggered by something (for me it happens to be sunburn, sounds like it could be stress for you if you do in fact have it). Also, Paul is correct, it is painful, however when I got it the few times I have, it was just a small rash (couple inches around) usually showed up on my chest. That is about all I know hope it helps, again I would highly recommend going to see a doctor.
