There is a very low incidence of inflammatory nodules associated with the use of hyaluronic acid fillers. This is basically a foreign body reaction. You're right in that antibiotics have been reported to improve this hypersensitivity reaction. Topical or oral corticosteroids or even corticosteroids injected into the lesion can also help as can hyaluronidase injected into the lesion. Sometimes these lesions can resolve on their own. You should return to the Doctor who placed the hyaluronic acid to seek a definitive resolution.
