Delayed inflammation following dermal filler injections is a recognized, albeit infrequent, complication that can occur weeks to months after the procedure. This type of reaction often presents as swelling, redness, or tenderness at the site of filler injection. Interestingly, it can be precipitated by events that activate or upregulate the immune system. Such triggers include dental procedures, viral infections like the common cold or flu, vaccinations, and more recently, COVID-19 infections. The exact mechanism behind this phenomenon remains elusive, but it is believed to involve an immune response to the filler material that is somehow reactivated or amplified by these events.
The immune system, when stimulated by infections, vaccinations, or other triggers, may inadvertently recognize the filler material as a foreign entity, leading to an inflammatory response at the site of the filler. This is not a typical allergic reaction but rather an immune-mediated response that can lead to symptoms like swelling, pain, and erythema around the filler area.
In the context of your situation, where there is concern about an antibiotic potentially causing issues, it is more plausible that the underlying infection being treated by the antibiotic is the actual trigger for the delayed inflammatory response to the filler. To add complexity to the situation, it's important to note that syphilis can cause a non-tender sore known as a chancre, which necessitates careful evaluation. This is significant because such sores could be mistaken for nodules related to filler complications. You should consult a doctor who has expertise in managing such conditions for an accurate diagnosis and treatment.
