Can Botox Cause Bells Palsy Symptoms?

The development of your symptoms may be coincidental wtih the prior botox.  It doesn't appear that the Botox in the forehead would cause Bells Palsy-like symptoms in the cheek and neck.  See a neurologist.

I'm sorry to hear that you've had this problem. I hope it improves quickly. 

It is not possible for the botulinum toxin to travel from your forehead and glabella (where you had the injections) to the areas of your mouth and cheek - the nerve supply to the muscles in this area comes from a different direction (it comes out beneath your ear and then branches out to travel across your face).

I'm also not aware of any link between having botulinum toxin injections and developing Bell's Palsy through an allergic reaction, so I believe that in your case it has simply been an unfortunate coincidence.

Botox does not cause Bell's Palsy.  Botulinum is injected into facial muscles and attaches to receptors on those muscles, while Bell's Palsy directly attacks the main facial nerve.  Your Bell's Palsy is unrelated.
