Grade: 0
Day 1 - Bee sting (?) in middle of palm in left hand.
Day 2 - Palm quite red in a 5cm circle around the puncture site. Can't close fist.
Day 3 - Swelling spread to fingers. Bought antihistamines from the chemist.
Phenergan 10mg antihistamines. Started with 2 tabs 3x/day. Made me pretty sleepy but the improvement over the first 24 hours was amazing.
