Well I have not had this because I did not have good results with PT. A few thoughts though. Could you call the pt guy up and ask him why? At least you will know. Also could you still go and use that pool? Maybe they would allow you to with a small fee? I am sorry about this. I know things like this can impact one mentally. Not with this but other things similar I have had docs thow there hands up. Try to focus on the progress you have made and ways to continue it whether that be on your own or finding someone else who is willing to work with you.
