I had malar cheek implants over 25 years ago and am now worried one may be infected. It is not red and I do not have a fever but it periodically swells up and gets tender. This did not happen until a few years ago when I began having a series of various fillers injected in the same area to further augment my cheeks due to aging. The worst was evolence which resulted in hard lumps that finally went away. What are the signs of infection? Soap/ water also can make it swell or too much touching.
