I hope that you were able to start the anti-viral Rx within 72 hours of the onset.
I also got slammed with shingles in my early 40's. I was on Vicodin for pain. Hard to say which was worse, the painful blisters or the nausea & exhaustion from Vicodin. Can't believe Vicodin is a recreational drug.
I didn't do any exercise for 2 weeks except walk my dogs because of pain, nausea & a bra was an instrument of extreme torture. Luckily the weather was mild & I got away with wearing a tank under another shirt when in public.
On a positive note, I rode a 70 mile bike event three weeks (maybe 2) after the onset. Still couldn't wear a bra, used a shimmel under my jersey, & it wasn't a very fast time, but I'd regained my energy.
Apparently our immunity from childhood chicken pox wears off. I plan on getting a vaccine when I hit 60 so that I don't face another round of shingles.
