Oh gosh, it sounds terrible! My first P/t had me writhing and crying and she didn't care, but kept pushing down on my knee with both hands with all her strength and remarked, how she was surprised I wasn't screaming by now...
I requested a different P/T and it was the best thing I did.
Don't go back tomorrrow!!! rest and ice. Call you doctor and tell him about your pain. You cannot possibly do P/T if you are in pain. I felt the same way you did, I questioned whether or not I should of done this. I coulda tolerated my pre op situation a few more years I think. Yeah, quality of life was going downhill and my left hip started hurting everyday due to limping. But this forum really gives me hope hearing that others went through the same ordeal and came out in a better state. So take comfort like I am, that you made the right decision and the wisdom of others who went through this.
It's gonna be tough in the beginning, the pain unbearable at times, but you will see daylight. I was so depressed at my slow progress, but lo and behold, around the 3rd week, I saw a slight improvement in flex and lessened pain. Have faith and don't let that P/T hurt you. A couple days off is not going to do irreparable harm. You need to control your pain first. Wishing you better days. We will get better!
