Hi debw,
I have used PT a few different times. The last time I went was to work on my leg that kept giving out on me. During this time we also worked on balance. I have to say the balance stuff was kind of fun...I know, I'm strange
For balance: they had some type of foam mat that made it impossible to stand still and required you to try and keep your balance. The mat was always put in a place where I had something to hold onto. Not only was it to help for balance but to improve ankle and leg strength. It was fun!
Has the PT given up on you? Possibly

Don't give up on yourself.
Years ago I had broken my left ankle and was non-weightbearing for 7 weeks. I spent alot of time in PT from before surgery to after I was able to drive. When I started PT after I was able to drive the PT worked with me for a few weeks then released me saying that was the best it was going to get.
What!!!???
I wasn't even close to the endurance or strength I had before the accident. I was shocked and sad...then I got ****** off and decided I could and would get back to where I was...on my own. It took dedication and alot of work and time but after a year I had regained what I lost.
I felt like going back to that Physical Therapist and telling her "see I did improve and without your help" as a "in your face." Of course I didn't do it but it was a great experience in my mind

There are good and bad PTs. You may have gotten one of the bad ones. If possible ask your neuro for any recommendations and try again with a new PT.
Dealing with pain after PT is common and a PT will usualy even tell you this and how best to treat the pain as well as telling you to call if there is a problem after your session. Anytime you are using muscles or muscle groups you have not been using, there can be pain.
The key is not to overdo and for the PT to understand and know this.
