I had it as a freshman in high school. it was so bad they put my picture in medical books. I had it on my right side from my collar bone down to my right knee. basically draw lines down the middle of my chest and down my back bone and fill it in with shingles. Luckily it wasn't on my man parts. It happened while I was trying to make the high school baseball team. One day last week of tryouts I didn't realize that it was bleeding and the coach noticed it. He pulled my shirt up and and said, hell anybody that can play through shingles that bad gets a jersey.
I had just had sex for the first time a few days before it first started appearing, so you can imagine what was going through my head. As far as pain, I have broken my arm twice where the bones where poking out, and broken bones at least 8 other times, had a double hernia, and the only thing that compares is migraines.
