The second opinion idea is a good one. Like you, I went to the doctor for a numb leg, and a short time later I had a dx of MS. I wasn't looking for MS and neither was my doctor.
I understand what you are saying about wanting to treat the correct problem and not wanting to jump on the DMD. Get that second opinion and even a third if it will help.

Don't be afraid to seek a second opinion. It's part of the diagnostic process. If your current Doc is uncomfortable with you seeking one, I'd be uncomfortable with them.
It is so tough!
Getting dx'd quickly comes with alot of uncertainty. We differ a bit in regards to what brough us to the doctor - I had stroke like symptoms. After initial dx I went for a 2nd opinion to make me feel more confident. My doc suggested it, but I already had it lined up I was so sure he was wrong.
Maybe that is something that would help put your mind at ease too...Just a thought. It is tough - because you don't want to delay and risk further damage, but you feel you are not dealing with all some do :(
