He is right and it's more than important than anything else to fallow what he say about this parts.

Poor/ineffective PT/DC/ etc is a waste of $$ & time and may even set you back, do not stay if you feel like there is no forward progress, esp if things become worse with treatment.
After a few poor PT experiences you will finally find a really good one..

If it get worse and if they tell you it is normal you should think to go somewhere else. Where are you living?
