I’m hoping someone can shed light on this as I have been having regular fillers for 10 years or so with no issues at all in different areas of my face. However every time I am sick with flu or a virus of some sort my fillers swell up and feel sore to touch. This only seems to happen with certain areas of filler ie it has never happened to my lip filler and it always resolves after a few days Right now one side of my cheek and chin is swollen and sore as I’m recovering from a bacterial infection.
