Actually, BOTOX is quiee popular as a treatment here.. It makes sense - it is a neurotoxin, so if used under strict control, it can be used to relieve muscular spasm.. It is used to treat dystonia. My son was also treated with it - he has a condition called acholasia - where the sphincter muscle beetween the oesophagus and the stomach goes into spasm. I have also heard of it being used for tarsal tunnel syndrome. Hilary Blue
