It should yes: You may well have a sulfonamide allergy (sulfa). These reactions typically last several days. Benadryl (diphenhydramine) otc..Say 25mg by mouth 2-3 times a day will help. The situation is a little clouded by the flu shot. The symptoms may be overlapping a bit. The fever and chills may be your bodies response to the injection.

Maybe not: You could be having an allergic rx to the sulfa. See doctor asap.
