How to remove lump on butt from hyaluronic acid butt filler?

Lumps or hardness after dermal filler injections like hyaluronic acid can occur due to a few reasons, such as an inflammatory reaction to the filler, formation of granulomas (small areas of inflammation), or improper placement or technique during injection.
Hyaluronidase can be used to dissolve hyaluronic acid fillers, but sometimes it may require more than one treatment to completely dissolve the product. If you still feel a lump after the Hyaluronidase treatment, it could be that not all of the filler has been dissolved, or it could be due to some other underlying issue.
Cortisone shots might be an option if the lump is due to inflammation or a granuloma, but this should be determined by a healthcare professional.
Surgical removal is usually considered as a last resort if other treatment options are not effective.
Using a massage gun is generally not recommended without professional advice, as it could potentially cause more harm than good.
It's very important that you consult with a healthcare professional who is experienced in dermal fillers to evaluate your situation. They can provide the most appropriate advice and treatment options based on your individual circumstances. Don't hesitate to seek a second opinion if you are unsure about the advice or treatment you have received.
