Fuck, fuck, fuck. I have a poison oak rash AGAIN.

Same places as last time... on my face. Those places have been hypersensitive since January. I'm trying to figure out where and when I could've gotten in contact with poison oak this time. Perhaps while in Golden Gate Park on Sunday after finishing the Bay to Breakers... But I didn't see any poison oak plants there, and didn't think there are any in the park. Argh.... I'm thinking of going in to see the dermatologist tomorrow, even before I get a referral from my PCP, to get a prescription for prednisone. Gotta stop this thing before it becomes a repeat of the last episode...
