Hi, Those symptoms make me wonder about possible TOS - You might also want to read about Thoracic outlet syndrome (TOS)
- esp if MRI shows nothing notable.

You can request a copy of the MRI report be sent to you , and that will give you time to do some research if anything shows up on it, and you'll be able to ask better questions when the dr has a follow up with you..
