His hypothesis is that this is just coincidence. The hydrocodone caused so much histamine to be dumped into my body that I'm reacting to stuff that I normally wouldn't even notice. Apparently ibuprofen can interact with this somehow, so I'm off that, too. I'll substitute tylenol as a painkiller, benadryl for the rash, and hydrocortisone for topical matters. I also have the standard instructions to watch out for anaphylactic shock, which I knew about already, but the reminder never hurts.
So today I'm going to be doped to the gills on benadryl. I've found an HD broadcast of the Indy 500. It looks really nice. Maybe Danica Patrick will win this year. Maybe Marco Andretti. Maybe somebody else entirely.
I remember the mini-controversry over the words that would start the race when the first woman drove in the field. That seems so silly now. "Ladies and gentlemen, start your engines!" works just fine.
