Those tests usually only show if there is an actual nerve issue.

Look into delayed pain & referred pain (goes back to trigger points)

MDs & surgeons mainly want a clear cut issue showing on testing, (something they can show for proof of ongoing treatment or RX, surgery) and often they are not too much help unless they studied beyond the norm and learned about soft tissue and whole body healing..

It is good to have that testing to rule out possible medical/surgical issues..

soft tissue, internal scar tissue & trigger points can impinge and cause just as much pain & symptoms and actual direct impingement.
Expert PT, DC, body work & lots of self care is a good thing to seek out.
If you need a MD referral.. find who or a few you want to try and ask for referral to them.. If they don't work out ask for a change to another place.
Going to a PT, DC or other place and asking questions is a good way to gauge them.. often The PT might come out and talk with you if they aren't busy..

Many professionals don't care for us to ask or know more than they might know..so some times we have to word what we know into a simple question..
