Pain from Botox Injected into Scar Tissue on Face for Migraines?

injection of scars is often painful, whether it is a corticosteroid, local anesthetic or Botox. Scar tissue is dense and replete with nerve endings when acute. mature scars may become more numb as time goes on.  Topical ice, cold blowing air (Zimmer cooler) and field blocks with local anesthetic, if practical, may help.

If there is scar tissue in the area of a Botox injection this can be very hard to make for a comfortable injection.  Botox does have a positive effect on scars.  You could try icing the area or using topical numbing cream but that would only get the skin numb, not the muscle area underneath the skin that needs the Botox. If it is really an issue nerve blocks could be tried but this may be overkill for a quick injection.  After a trauma the nerves may be hypersensitive.   This is  not an issue in a normal Botox injection for migraines without previous trauma.
