This is not a normal reaction. There maybe several reasons for this, including biofilm infection, granulomatous inflammation (either due to the filler or the start of granulomatous chelitis), plus other medical conditions.
The very first step is to obtain a diagnosis before treatment.

The majority of swelling if not all should have subsided at this point.
The majority of swelling if not all should have subsided at this point. Schedule an appointment with your injector to discuss your options. If you are unhappy, having the product dissolved may be your best option. It is common for lips to have a slight increase / decrease in water retention.
See your injector
Please see your injector for a physical examination of your lips. Hyaluronidase may help, but this could be caused by something else.
Dissolve filler or wait
While Volbella is not currently an FDA approved filler in the U.S., it is still a hyaluronic acid filler which can be dissolved. Since the nodules are new and have not been there all along, it would be best to see your injector for an in-person evaluation to determine what has caused the nodules - the filler itself, some type of reaction or infection?, or something else.

3months post filler
Thank you for your question. Since it has been 3 months already, I would suggest seeing your provider for further evaluation. Good Luck.
