I don't agree with amandalouise. I suggest you read about MS on the Internet and see your primary care doc. If he/she thinks you might have a MS, then you will be referred to a neurologist.
The process of being diagnosed can be a long one, and I have never heard that just looking at someone will seal the diagnosis.
In addition, MS could be affecting one part of the body, but not another. If the hands are not affected, then you can type.
Also, MS patients generally live a normal life expectancy, so don't worry on that account.
I hope you don't have it!
