my rule of thumb with doctors,is,,,dont rely on them,trust your own judgment,my doc said,,you will have this for the rest of your life,,,well,,she was wrong,,and remember,docs dont know what causes tn,,so why should anyone listen to them,,,i didnt,,,i searched,and found the answer,,no more tegretol no more pain killers,,, and common sense says,,,all these people with the same symptoms,same meds,same pain,,same cause same cure,,,there is but one kind if tn,,thats tn,, bilatteral tn,is just an exstention of of basic tn,,,its a progression from one sided tn to two sided,,thats the clue,,,that allways told me,,this tn, has nothing to do with the nerve,,,its the brain,,,,
