Hi i was going though the TOS sights to see if i could find some info and i ran across this i thought it might be handy for any one living in the US. There are clinical trials for a drug botulinwm toxin type A injection botox. So i would say this must be free being that they are recruiting TOS. Any way if anyone is intrested the sight it was on was http://www.ninds.nih.gov/disorders/t...c/thoracic.htm hope it might help some one.
