Bump on Forehead from Botox

Botox is dissolved and its effects gone after four months, latest five, after injeciton.  If there was an immediate lump after injection, there might have been a hematoma which then soldified after the treatment.   The slight bleeding could have caused a focal calcification in the area leaving a permanent bump.

You should see your injector to check the bump out, as it is unusual that it should be there for so many months after your treatment.

I true bump after Botox is unexpected. I have had several patient report a contour irregularity after Botox. It was located in the midline and we figured out that it was a part of the frontalis muscle that had not been treated adequately and was pulling more than normal. What I noticed is that there was new ridge about halfway down in the middle and a little depression above it. When she lifted her eyebrows it got worse. Treated by adding Botox in the midline. Hope this helps.
