Stop the tens unit. Then before your next therapy appt, sit down with the therapist and say "I have some concerns." 1. the tens unit is extremely painful and not helping at all. I will not use it again until I have a chance to speak to my dr. 2. I do not focus on my rsd spreading. It just so happens that everyone is different and some people go forever and not have it spread, others it spreads immediately. 3. Please do not compare me with other people. I realize PT is a good thing to have, however, everyone is different and everyone responds differently to PT, please don't compare me.

Now if she cannot accept any of the above. Make an appt with your doctor and let him know all of the things you have talked to her about and are not happy because she will not accept one or all of them and you need a new person.
