First noticed it yesterday at work, by this morning I had a nice series of blisters and puffy skin on my right eyelid. Left work early and saw a doctor, yep, I have shingles. Got some acyclovir (BIG dose, 800mg 5 times a day) and set up an appointment with an opthalmologist for 8:20AM tomorrow morning.
I should clarify: I've previously had chicken pox (when I was 4 years old or so), so this is just a recurrence; it's painful and puffy, and it carries some risks (namely eye infection+scarring), but it's not as bad as it would be if I didn't have chicken pox before.
And I'm not really contagious, thank god.
