"I guess" another doctor is about to bite the dust

I was having trouble walking,extreme pain in my legs and dr put me through all kinds of tests, x-rays circulation and was setting up an appt to see a nerve specialist. 14 months ago. I have been seeing a physiotherapist for some relief. 3 weeks ago the problem went away during a physio treatment. One click in my low back. Sciatic nerve was impinged. So now to get straightened out after all this time of muscles being in spasm…tiny improvements daily.
So not sure, would the nerve specialist have figured it out?
