Hello Twilly,
Have you read anything about Thoracic Outlet Syndrome (TOS)??
or double crush syndrome = TOS & ulnar or TOS & carpal tunnel?

Do you have neck or upper back pain/tightness?
C spine is OK - no possible causes from it?
What caused the ulnar problems to start up? acute accident/injury or repetitive/desk types of work?

We have a TOS forum with lots of info and various therapy & alternative care.
Here's the useful sticky thread link-
