Did Dysport Travel into my cheek, lower jaw and part of my neck or can it be nerve damage?

Thanks so much for sharing this experience. I do not believe your Dysport has traveled down to your cheek  as it is anatomically impossible to move down there from where it was injected. Either way, Dysport is not permanent and typically does not alter sensation. Best, Dr. ALDO :)

No one has permanent damage from these injections.  There is some nonsense out there on the internet.  Try to ignore it because there is no truth to it.  It is much more likely that you are experiencing referred pain associate with the treatment.  There can be subtle (and not so subtle) systemic effects of botulinum toxin treatment but generally these are very mild and short live.  50 units of Dysport is a very small dose.

There is no anatomic reason this can or should occur. The Dysport is localized and won't cause the symptoms you describe. Nothing with Dysport is long term and all results return to normal after about 3-4 months.
