Injected Sculptra 12 days ago. Now I have a swollen red lymph node.

i injected one vial of sculptra 10 days ago. only on the sides and jaw. now on the area near the chin at the injection site i have a swelling and a red area in one point. my jaw looks heavy. it has bern like this for two days. my internist said i have a swollen lymph node and gave me amoxicillin. What are the chances of biofilm infection? he said it is impossible for sculptra to cause biofilm infection, but i read otherwise. my dermatologist told me it was hematoma, but that was ruled out today.
