Welcome to Mayo Clinic Connect, @user321369. Most research about injectable fillers seems to indicate that filler should not move after injection, but that also depends on the area treated. That being said, "it still is possible for filler to move from its original location and for lumps or bumps to appear in a different area than where the filler was injected, although this is uncommon. If this does occur, it could be due to several factors including poor injection technique (using too much filler, or too much pressure when injecting the filler), incorrect massaging of the skin after injection, or pressure-induced displacement and intravascular injection (injecting the filler into a vein or an artery).” https://www.sciencedirect.com/science/article/pii/S2352587819300178

Hyaluronic acid fillers, such as Juvéderm products, Restylane products, and Belotero, can be partially or completely removed with an enzyme called hyaluronidase. https://www.americanboardcosmeticsurgery.org/injectable-treatments/can-you-undo-dermal-fillers/

I’m also tagging @hopeful33250 and @contentandwell to see if they might be able to shed some more light on this matter.

@user321369, can you go back to your practitioner? They would be able to best guide you, especially with regard to massage technique.
