I have the tingling sometimes now but mostly mine is the severe pain.Before my pain issue I was complaing how I felt my legs couldn't walk. Its hard to explain but like they were fatigues or so weak at times. I went to a physiatrist who did not help me and ended up going to the neuros. The physiatrist did do my first nc though. I'm not sure what else they do but I think more with movement and nerves. So that may help with your issue and the fatigue. If you have the specialist your talking with you may want to schedule an apt. I have found wait lists can be long. You can always cancel. Have you had all the blood work? I understand feeling like the mystery as am in the same and also understand rushed doc feeling. Sorry I can't offer more as the true experts here no more. Good luck
