I was dx with Relapsing Remitting MS, 7 years ago, my first set of symptoms was an area of numbness that gradually increased, tingling in my legs, numbness in my hands, walking felt like the ground was wobbly, like trying to walk on a bouncy castle.
My DX was very quick as I was in a private health scheme, it was a very scary time.
My advice to anyone finding themselves in this situation would be to stay away from google, as you will scare yourself silly and unless the info is from a trusted source it may not always be genuine,
MS is different for everyone. Assuming an RRMS dx, there are good treatment options available, that can reduce relapse rate. I am on my second disease modifying drug, and touching wood it seems to suit me.
Being diagnosed with MS has totally changed my outlook on life, I have had to make lots of adjustments to make my life easier. But you can do it and still have a good life.
The MS Society have a support line and a forum, that may be helpful to you for support. The MS trust also have lots of information too.
Good luck.
