Sorry you had to have the ulnar surgery and then find out that it wasn't the only problem..
Could have been a double crush syndrome - TOS = cubital...

Tests often come back normal w/TOS.

How long was the PT for?
1 set of sessions (4-6 wks?) usually isn't enough to make much difference..but it won't help & can make you worse if they are doing the wrong types of PT..

How long have you had sx of TOS?
Any thought on what may have caused it for you?
