Into approximately 6th week of allergy shot therapy. Yesterday, around 1:30 p.m. rec'd injection and I immediately started itching at injection site on left arm. It made a weal about the size of a dime. Told it was ok. It itched all evening, and still itches this morning. The swelling went from size of a dime to size of a baseball. At 6 p.m. I took black marker and made spot marks around it to see if it increased or decreased. It increased. I took Benadryl also, which seemed to help the itching. No other problems but wondering now if I dare have the next round of shots. I looked up reactions and it's not uncommon to have this happen but usually subsides in 4 to 8 hours. I am well past 8 hours.
Advice?
