I am a 51 year old who has been diagnosed about 6 months ago with Spasmodic Torticollis. I am a flooring contractor and have had large exposures to solvents from moisture cured polyurethanes.( Toluene Diisocyanates ).I developed Asthma at every exposure - at the same time developed Spasmodic Torticollis. Does anyone have any evidence that exposure to solvents can cause S.T.? I have a book entitled "chemical sensitivity". This has made me concerned athough its hard to prove definitely. Can anyone help Please?
