Why is it like pulling teeth to get an MS diagnoses?

FINALLY! Somebody else understands!!!! Ok, sorry. I just lost it for a minute. MS is so frustrating. Not only does having a lesion not necessarily mean you have MS but having no lesions doesn't mean you don't have MS either. And since the symptoms of MS can seem vague or not physically seen, most doctors think their patient is either making it up or being a hypochondriac. I completely understand your concern yet I haven't found a way around it yet. Been to several specialists, none helped. So if you get a diagnosis, PLEASE tell me what the deciding factor was. :)
