My daughter has had hives for 3 days. Got a shot of prednisone yesterday and prescribed 5 pills over the next 5 days. Also taking benadryl at night, claritin in the day. The hives are worse, all over her face and body. Now some bruising, and ankles swelling. Should she continue to take the prednisone or could she be allergic to it? It did clear up once during the day but got worse at night. What to do???
