Bingo! I went undiagnosed for so long because I just stubbornly kept going to work thinking "Well, it's just migraines, I'm unlucky".

It took much more distinctive symptoms (L'Hermittes Sign, namely) for me to realize "Okay, something's not right..".

I had gone at least 2 years with left side pain under my eye... my short term people at work (disability) figured it was dentistry gone wrong, then went the sinusitis route, etc.

Whodda thunk it would end up being MS?
