Bump After Botox? I got botox Between my brows 3 weeks ago and have this linear bump going from the inside of my left brow up.

Hi Kristen
BOTOX is administered by injection. This can introduce skin pathogens into the skin. The amazing thing is how rare skin infection is despite the frequency with which these treatments are done. A skin infection following an injection usually presents within two or three days as a small tender nodule. Because the circulation is very good in the areas being treatment with BOTOX, the body can usually resolve this focal cellulitis relatively rapidly.
However, these often benefit from local care with warm compresses and oral antibiotics. While is it customary to prep the skin with alcohol, in my office, patients with a history of MRSA (methacillin resistant Staph Aureus), receive a betadine skin prep like that used to prepare the skin for surgery before a BOTOX or Restylane treatment.
If your lump persists, bring this to the attention of your treating physician.

Hi Kirsten. If the bump has gotten smaller and less sore, that's good news. It sounds like you have a bruise with some blood buildup that's slowly dissipating.
For safety's sake, you should always return to your practitioner anytime something like this occurs just to rule out anything more serious. If this is a bruise with a small clot, it should resolve on it's own, but schedule a checkup anyway. Good luck.

It is impossible to tell what caused your bump unless you are examined. If a physician had treated you, I would recommend you return to that doctor and ask for them to examine you and explain what it is that you have and what might have caused it. They should have a better idea than anyone else.
