Hi Sharon.
I posted part of this in the other thread, but I figured I would share on this post as well.
My brother's wife has been living with MS for many years. She has been lucky to be very responsive to treatments and even had a good remission during her pregnancy a few years back.
My great grandmother had MS but they were unable to diagnose it properly back then. At one point they were able to go back and look at her medical history and realize what it was.
I also work with 2 people with MS and have a close friend who's wife has also been diagnosed. All have varying symptoms and all respond to treatment differently. To some they get by with a minor annoyance, to others it's a daily struggle.
For all of the people in my life as well as all those I have not met yet, I have been riding the MS150 (150-mile bicycle ride) the last few years and raising money to help find treatments and hopefully a cure. This year I'm about to bust through the $1k donations goal and I don't plan to stop raising donations until the weekend of the ride in September. There are many of these types of events (walks, runs, rides, dinners, etc...) throughout the country and I highly recommend getting involved in any way you can. There are great support groups available as well as a wealth of knowledge available online and through your regional chapter of the MS Society.
My best wishes to your son and his family (and of course you).
