Had nose filler about 7 years ago, most of it reabsorbed besides a big lump at the root of my nose. What should I do now?

If someone gets HA filler, a persistent area may be improved with the dissolving enzyme in many cases. I believe that would be the next best step. I hope this helps. Sincerely, Dr. Joseph

It is hard to answer this question without knowing what your nose looked like before that initial filler several years ago. Also, we would need to know what type and how much of the filler was used.
Generally speaking though, most fillers should have dissolved within 2 years of the injection, though some "dissolvable" fillers can last up to 5 years (unlikely).
On the other hand, if a permanent filler was used (e.g., silicone, artefill), then that will not dissolve and you will need a surgical correction in Rhinoplasty to remove that "bump" that you are describing.
My advice to you is to consult with some experienced in both surgical and non-surgical rhinoplasty (e.g., a board-certified Facial Plastic Surgeon) so that you receive an expert and unbiased opinion.
Hope this helps!
