Why is there a lump from Botox in my chin and is there cause for concern? (Photo)

You typically will get some injection-site swelling immediately after treatment but this typically lasts just a few minutes.  I would recommend that you follow-up with your provider for a proper evaluation.

That is not a rare occurrence after having Botox injected in your chin. Sometimes adding a drop more can even it out, but sometimes its best to wait until it has worn off.
