After PT

I am in so much pain after PT appointments that I dread going back next week. My therapist says only to let it get to like a level 2-3 and then tell him to stop. But it’s like I feel bad to say stop or I feel like I need I be stronger and suck it up or something . It’s terrible. Feel like I was beat by a wooden baseball bat and now I’m supposed to try to go to sleep. Anyone else ?
