Lumps form 3 months after I get filler in tear trough, why is this happening?

Hi @RunnerGirl61. I'm sorry you are dealing with this. You can return to your injector and have the filler reversed with Hyaluronidase. Best of luck, Dr. Nima!

It would have been helpful to see a picture but it is always best to have an in person consultation.  If you had HA fillers injected, the bumps can be either softened or eliminated with Hyaluronidase injections. Bumps can happen and their act cause is difficult to determine, it might be the product, the injection technique, any recent infections you had, if you suffer from seasonal allergies, or if you had any recent dental work, etc. Too many to list. Time or Vitrase are your solutions.  Please see an expert. Hope tis helps. Best, Dr. Avaliani

This is difficult to answer without pictures and needs an in-person evaluation. If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. See an expert. Best, Dr. Emer

Injecting the tear trough can be very challenging. Complications are common. It sounds like you may have developed some scarring or some residual filler. A consultation with your plastic surgeon is in order. The "lump" can be treated with hyaluronidase to break down the product.
