I've had neck, upper back, and mild lumbar pain for 8 months now coupled with leg issues for more than a year. I finally got a lumbar MRI done and it showed a syrinx whose full extent is unknown -- I need to get MRIs done of my thoracic and cervical vertebrae this week.
In the meantime, if this is what's causing my symptoms, I need to know how to keep it from getting worse. I play bass in two bands and guitar in a third. I recently bought a very light bass, but it still makes my neck and shoulder a little sore. By standing up and playing it am I running the risk of worsening the syrinx?
