What are the symptoms of an allergic reaction to Sculptra?

I apologize for keeping post similar questions, but I can't tell if my issue is due to normal reaction to sculptra, infection , overractoin , bad skills of the injector , allergic reaction to sculptra or even immune disorder . 4.5 months post 1 vial sculptra injection the volume still growing vigorously ,I've been taking antibotics , arnica oral and topical for a month now .4% kenalog shots helped, but sunddenly I got swelling and soreness, volume all came back right after that.
