How do you know if you have multiple sclerosis?

You dont always ..... my wife was diagnosed in 1990 but I think she had symptoms when we first met in 1979. There is such a variety of similar central nervous system disorders that diagnosis is often unclear. Initially, doctors thought she had a trapped nerve in her wrist ( carpel tunnel ) which was totally wrong. But there are diagnostic tools that together will pinpoint the condition, but normally only when it becomes more pronounced. But hey, you really need to be asking a doctor for an opinion here .... I guess from your question that you are kind of scared about it ....totally understandable .... but self diagnosis is stupid and going to make you a mess if you add two and two and make five! But believe me, you are better off seeking a conclusive medical opinion rather than sitting on Yahoo questions worrying about yourself .... take care ..

Go to your doctor. Immediately.

There's a website listed below which lists the various symptoms, but my initial advice stands.

you call your doctor and get checked out.
Go to the doctor and get some blood tests.
It would be difficult without a proper test.
Go to the doctor cos i aint got a PHd
