Yes, I got them years ago, in my eye and around my armpit.
Shingles is a two-stage infection - first of all you are afraid you might die ... then you are afraid you might not!
Actually, joking apart, although it's painful, it is unlikely to last a long time, so do get plenty of rest and fluids inside you. Although it's a strain of the chicken pox virus, it is often exacerbated by stress, so take it easy in the future to prevent a recurrence.
There used to be an 'old wives tale' that if the rash met around your middle you would die - which is nonsense, but as mentioned, you may feel like it.
Keep the painkillers going - try to overlap your dose if things are really bad, and have three before you go to sleep, and a couple more if you wake in the night.
You will get past it, but it's nasty, my sincere sympathies.
