Filler in my chin is really hurting, is that normal?

There should be minimal pain after chin filler. I would immediately seek evaluation to make sure there is no evidence of infection or vascular occlusion. You should feel it but very mild discomfort only.

Yes this is normal to have discomfort in the chin area after filler and this can last several days, depending on how much filler has been injected. You can try OTC pain reliever to manage the pain during this time.

Thank you for your question.  There are several muscles that move your lower lip near the chin area.  Injectables in this area can stretch these muscles and cause some soreness.  Some swelling in the area of injection can be expected.  However if you are feeling extreme pain in the area, that could be a sign that there is something going wrong (like injury to the blood vessels or excessive compression of the muscle) that would need to be reversed to prevent injury to those muscles.  If that is the case, seek immediate reevaluation by your plastic surgeon.
