Still a big ball after 18 months & symptoms are getting worse, concerned I'll react to dissolver too, advice?

Hello, and thank you for your question. Filler can take time to dissolve, but even so, it may never fully go away even after the intended timeline has passed. Hyaluronidase is an enzyme that breaks down hyaluronic acid. Although allergic reactions can occur, it is not always common. If you are allergic to bee stings, this can be a contraindicated use for hyaluronidase. Some clinics will test spot a small area on your forearm to see if you have an allergic reaction to the enzyme before injecting a larger amount to dissolve. Although this is not fool proof, it can help guide to potential allergic reactions. It is difficult to predict if you could have an allergic reaction. I would suggest following a practitioner who can better guide your treatment plan. If you are ever concerned about your immediate health, please call 911.

I'm sorry to hear of the issues you are having since your filler injection. It's difficult to determine why you reacted to it this time and never have in the past. The most reliable way to dissolve the filler at this time is using hyaluronidase. You can also allow the product to be metabolized gradually.
