Shingles BITES. I don't want to imagine what it would be like with chickenpox at the same time.
I have had shingles twice. The second time was the full outbreak, which then progressed to big blistery, itchy chicken pox on top of skin that just sat there and hurt. You know what I am talking about. It just HURTS. It doesn't throb. It doesn't feel like it's been scratched. It doesn't have a dull ache. It hurts. And hurts and hurts and hurts. Awful.
You will be pleased to know that the first time I got shingles I had no rash, no breakout, nothing, except in one little place, and invisible place. I went to the doctor dying of a brain-tumor-style crushing agonizing hurts-to-see headache that lasted a week and and wouldn't go away.
Checked me over, and looked in my ears and whistled. My first outbreak of shingles was only on the inside of my left ear canal. It was pain so bad, for so long, that no drug helped but perscription narcotics (and that didn't really help). Awful.
I had shingles on my face and in my eyes. One cornea is permanently scarred. The pain was off the charts.
