In the US they have to provide them, but I am sure some Ts do get defensive. I imagine their might be a fee for making copies, but I can't imagine it would be much. (I think I was switching some dr. in the past and got charged $10 to have my records copied and given to me for the next dr.; this was not a T.)
If the T had an office staff and I was worried about the T's reaction, I would probably start there. But in the US you are entitled by law to see your medical records.
