I have been able to treat patients effectively with kenalog injections. Usually on palpation the branch of the trigeminal nerve causing the pain can be identified. Its usually either supra orbital, supratrochlear or infraorbital. Then I inject 5mg of kenalog into the nerve itself using 30gauge needle with 0.5cc of Kenalog 10.
It takes the pain away for about 3 months. I have not use Botox in the nerve but in the muscles of chewing with some success.
You should look for someone who deals with these issues regularly in the specialty of neurology or otolaryngology.
