Shingles can most definitely occure more than once. cite. “Shingles is caused by a reactivation of the dormant virus in the nerves of people who have previously had chickenpox. As as a result shingles can unfortunately occur more than once.” This is actually the first time I’ve ever heard it suggested otherwise.
Yes, it does sound as if you could have shingles. The difference between shingles and Herpes I, symptom-wise, is that shingles pain travels along the nerve pathway, whereas Herpes I hurts, but only right around the sore. So if the pain is following the path of one of your facial nerves, shingles is a likely bet.
One of the other significant things about shingles is it is always one-sided. It does not cross the midline of the body in one outbreak, because the nerves don’t cross the midline. While you could end up with an outbreak on the other side of your body in the future, it would be from a different sore(s), on different nerve pathways.
Stop scrubbing at that crusty stuff. There may be active viruses in the puss, and you don’t want to spread it to other nerves. You also don’t want to be around older people (above the age of 12), who have never had the chicken pox or the chicken pox vaccine, because your shingles goo has the same virus in it that causes chicken pox. (I would encourage parents of littles to bring them around you, myself, as having pox as a little is generally not dangerous, and the immunity conferred by having the disease is longer lasting than the immunity from the vaccine, but that’s just me. IANAD) Don’t let others drink from your cup, use the same washcloth or towel as you, and for Og’s sake, don’t kiss anyone.
(Can you tell I grew up in a household with herpes? Mom has it from her mother kissing her goodnight with a sore. None of us kids nor my dad caught it, because we were all careful.)
Because it’s on your face, you should go see a dermatologist. She can tell you whether it’s on a nerve pathway which leads to your eye, which could be potentially dangerous. If it is, she will probably prescribe anti-viral eyedrops.
Of course, she can also tell you if it’s not shingles, and give you some good information on minimizing outbreaks in the future.
