Hi Dr, I think your site is first class. I have a question about botox injections for voice problems. I heard it can cause swallowing, eating, swelling, breathing problems and others. Could this be true and how dangerous is it? I just read today about a Dr Mort Cooper who claims to have a natural cure for Spasmodic Dysphagia, which from the sounds of people speaking on his videos sounds like my condition. He calls it Direct Voice Rehabilatation. (DVR) Have you heard of it and would that be a feasible treatment?
