Hit my head very hard 2-3 hours after Botox in my jaw. Will this affect the outcome of my procedure in any way?

No, it is unlikely that hitting your forehead will negatively impact your results. Keep in mind it can take 1-2 weeks for final results with Botox. Best, Dr. Emer

There should be no effect on the outcome of your Botox treatment to your jaw from hitting your head.  The product is injected into the muscle and would not be impacted by a blow to a different part of the head.

Thank you for your question. The effect of Botox should not be affected. Please make sure that you do not have any other injury.

In my opinion, hitting your head 2-3 hours after receiving Botox to slim your jaw and help with TMJ should not affect the results of your treatment.  

A knock to your head is very unlikely to have any effect on the outcome of your BOTOX®, particularly as it was injected into your jaw. Remember that it does take between 7 and 10 days for the results of BOTOX® injections to fully develop, so try to put the knock out of your mind and relax. As an aside, you should get checked out for any injuries to your head, if you haven’t already done so.
