Jo*Mar makes a good point.

I had severe numbness with my left arm after my injury in 2001 and a similar problem a few years earlier. My chiro suggested some diagnostics for TOS. I found a physiatrist who diagnosed TOS and got me to my fabulous PT.

At the earlier time, I asked about MS. My neuro said that MS shows up on an MRI like Christmas lights. I needed PT to resolve some issues with C-6 to T-3 and related problems. This resolved the numbness.

I understand how anguishing it can be to get an MS scare. It does not look like it is worth worrying about.

Wait on your doctor's report.

As was mentioned, if it was MS, you would likely have been notified quickly.

My best to you.
