Farmgal, Welcome. You will find many wonderful and supportive people on this site. I am not as informed as many on this site, so I'm sure they will soon offer you some good advice. I will keep you in my Rosary prayers.
Thank you for the info, my dr. just seems to want to adjust my baclofen and I quess that would help to . But its a good thing to laugh, I found out fast that you can only cry so long then you have to hold your head up, eyes down and everywhere, and if you hit the floor and are not hurt youcan laugh ! We jjust put in wood laniment flooring, and guess what when you fall the furniture pushes with you, heck I redecorated many time !I've only fallen backwards once and that was with help. Someone left a dish that we feed the dogs with in the middle of the kitchen floor. Its just a small plate sitting on a linoleum tile floor. Well I wasn't watching where I was going and stepped on it. My legs were doing well at the time so I'm sure it would've been quite a show watching me ice skate around the kitchen while I try to catch up with my foot on the plate. In the end the plate-foot was faster and down I went.
Relevant, not really but I laughed once I got up.
What happens though is your reflexes slow which in turn causes the loss of balance. By the time the body catches up with what's happening you're on your way to the floor. Its different for everyone and is also affected by which muscles are weakening.
Hand spasms for me are an on and off thing but do happen more often if I've been typing a lot throughout the day.
