Is it possible that after a week of rash and 10 days of pain it spreads to the eye? It's right eye and I have a rash on the left side. I woke up with a feeling of having something in the eye and I still have that feeling, the eyelid has a red part, it happened before on that eye, a lot of times (I don't know why) but since this happened to me I am afraid that it isn't a stye or something like that but shingles instead, the beginning of it. I am taking anti virals since Monday.
