Is my case really "rare" or "unique"?

My doctor told me my case is unique and rare, is this true?

I have gone through some major events in my life in the past four months, and about a month into them I started getting headaches. Nothing too terrible, but everyday. That progressed into pretty much all day everyday and my entire body tingles on and off in different places also. ( Once nothing tingled but a tooth, once it was just my gums ) I also had an ectopic pregnancy which was treated with injections of metha or mexa something or other, and the tingling and headaches stopped for a week. It SEEMS like the more stressed I am the worse the headaches are but I cant be sure. Also, I had what they think to be a mirgraine two months ago, where my vision was weird (two large half moons that started as "sunspots" and i couldnt see anything where the moons were) and i was talking and thinking weird.

I had an appointment today and my MRI came back clear, I had a full panel of bloodwork done that was also clear. I was given Ativan and Axel and neither worked. Today my leg (from just under my knee down) started hurting and at times i can barley but any weight on it, who know if its related. I have to wait months before I can see a neurologist and an opthamologist and I am really worried and stressed out. I am 22. Any opinions?
