Juvederm - Oklahoma

I have had juvederm to help smooth my skin out because I have loss of collegen from age. Im 48. Ive always had great success. The last time, also but just couple days ago, which is about 3 weeks after Juvederm, I have a small white bump that came up and after the juvederm, it looked like a round white scar area, but not raised, now it appears like a small pimple size raised. Appears to feel like theres a point on it, feels like a pimple. Im wondering if 2 weeks later this could occur and if it sounds like it is the juvederm? Ive put zit meds topical OTC on it last couple days no change. Im not sure if really a pimple or juvederm. Any ideas.. My doctor was running behind that day and I felt rushed in the office during injections and afraid did not get my $ worth, which is a shame because always been amazing prior vistis..
