So I woke up Thursday with a few spots. Friday morning at 6 am, both of my elbows looked like this. So I paid a stupid copay for the doctor to tell me to take Benadryl and that hives could be from anything. Gee, that was helpful...I still have NO IDEA what it is from. Needless to say, yesterday I washed all the bedding including the blankets in HOT water! ARGH.
