I'd run out of Aerius, the allergy drug I take, for a few days and so wound up not taking any for a few days. That turned out to be a HUUUGGGEEEE mistake.
The red blister things have re-appeared under my fentanyl patches and are itchy as crazy. So not only is my back kind of ugly due to overlapping patch areas, it's ugly AND itchy due to the allergic reaction. Blah.
To counteract the allergy effect, I took some Benadryl which acts as an antihistamine. I then tried to watch a movie. Ha ha ha - it's funny because I fell asleep during the movie (Benadryl is known to make people sleepy) and woke up watching only the movie menu. That's a bit of a waste of a movie, wouldn't you say?
