2nd Day After Upper Lip Filler but I Feel a Lump On Left Side of Lip. Will is Dissolve or Settle?

It is not uncommon to get some small lumps after lip injections as the covering of the lip is so thin. Some times this can be gently massaged out. Often times it will settle after two or three weeks. 

Having a lump or bump post Restylane is not uncommon. Waiting 1-2 weeks is generally advised, and then important to follow up with the provider for proper assessment. You may need some general massaging or further treatment, or it may settle down on its own.

There is no way to tell at this point in time. I would give it 2 weeks. At that point, if the lump is still there then it is due to a collection of filler and can be reduced using an injection of hyaluronidase (assuming you had a hyaluronic acid filler). It may simply be due top swelling (often is asymmetric) and may very well go away on it's own. At this point don't worry. Be patient. It can be addressed if it needs to be in a couple of weeks. Good luck.

If the lump or bump is still there after two weeks then hyaluronidase can be injected into the dump to dissolve the annoying bump.  It is a simple and quick fix.

It is always advisable to wait at least one and preferably two weeks for all of the lumps and swelling to resolve before assessing the results of filler injections, especially if they are hyaluronic acid fillers like Restylane, Juvederm, or Belotero in the lips. I recommend waiting several weeks for the swelling to go down after the treatment before worrying about any long-term adverse effects or considering any "touch-up" treatments such as additional filler injections or reversing the treatment using hyaluronidase.
