Juvederm injections sore and swollen months after procedure.

This is an unusual occurrence and should be evaluated by your doctor.  You should see improvement now that you have begun antibiotics if it is from an infection.

Thank you for your question. Yes, it is possible that the infection has spread to the areas that were injected with filler. I recommend having a follow up with your injector for evaluation and treatment. Your injector will probably want to treat this with antibiotic and possibly dissolve the filler. Best of Luck!

Thank you for your question.  I'm sorry to hear that you are experiencing delayed swelling and tenderness after your Juvederm treatment.  It is impossible to make an exact diagnosis or specific recommendations without assessing you in-person.  That said, it is possible that you are experiencing an infection in your filler, as others here have suggested.  I have also seen a small handful of patients who experience significant delayed swelling of their fillers, particularly around the mouth and lower face, shortly after a mild illness or seasonal allergy flare.  I suspect this is more due a heightened immune response to the fillers than a true infection.  Regardless, in any case, I would recommend a thorough evaluation by a cosmetic dermatologist or plastic surgeon with extensive experience in managing filler complications.  Best of luck.
