Try someone who specializes in active release technique. I see it is something across the pond as well. It is more a cross between eastern and western approaches to total body alignment for optimal functionality. Chiropractic but more focused on muscles. I would say it is accupressure.

I too would stay away from Botox especially if there are any neuro or muscular issues anywhere in the body. The main side effect is difficulty swallowing so if you have that it sure doesn't make sense you would want to make it worse.
