I used to get shots(3 in each arm, 2x week). Everytime I would experience really bad swelling at the injection location. It would be about the size of a silver dollar and really red. It really does help it to go away faster if you take an antihistamine. I took benadryl in addition to Allegra. You might want to ask your dr if you can take 2 antihistamines though.
