brain chemistry is not multi facited.,,,,,tn has one cause one cure,,,like every illness,,,we want a cure,not a palitive aproach,,,,,does a drunk person feel the same pain when sober,,,nope,,brain chemistry,,,is alltered,,,allmost every tn patient has identical symptoms,,one set of symptoms,one cure,tn is not multi faceted,,there is one kind of tn,,and only one,, we see variations bilatteral ect ect,,but the cause is the same,,the varyations are caused by how much amonia why have in our bodies,,,its the same reason for tn fluctuating nature...my rule is,,never become a compliant patient,never accept tn as incurable,,there is no mystery to tn,,,
