Sorry JIJI, I neglected to answer to part of your problem. Everyone is different, but I, personally, would not recommend ativan/tylenol for such severe anxiety (w/ stiffening and spasms). It may not be the best, but I take xanax. It is very addictive, but I have maintained OK for years. I don't take it til I can't stand it anymore and it does bring relief.
There are differening opinions, so you should ask your Dr. Some here take Valium, which is excellent for muscle spasms, still very addictive. Some say Valium is more addictive/dangerous than xanas, and some say vice versa. I take xanax simply because that is what my Dr prescribed.
I say there is a purpose for every drug and if one can give you some relief, proceed cautiously, but accept it.
