There are many here who had to wait quite a while for their dx. I agree with Sally in that your Neuro
should consider MS since two close relatives have it.
I had symptoms for years but never paid much attention to them since they were so mild. It was probably my third episode that forced me to see a doctor to find out what was wrong. I had double vision and couldn't ignore that! I had numbness in both legs prior to that (a couple of years prior) but wrote it off as a pinched nerve after it resolved itself after a couple of months.
If your Neuro isn't an MS specialist it might be a good idea to find one - or go to your Aunt's or sister's if they're close enough. The sooner you have a dx the sooner you can begin treating the disease.
There's lots of us here to help you through the dx process. Sometimes it's lengthy....sometimes it's quick.
