TD is more common when stopping a med than when starting one.

It sounds like you have EPS (extrapyramidal syndrome) which I have just been battling after starting a 2nd AP. They can treat the symptoms with meds. Cogentin helps a lot. I used valium for the rigidity as well. There are others that help. I had to come off because nothing was helping and the oral motor stuff was a problem but it can be successfully treated. It does need to be treated ASAP though because if it goes on too long it can become TD in rare cases.
