Hi Sgt Bob,
I was diagnosed at age 44 after five months of tests, doctors and stress. I had similar symptoms to yours that caught my attention. When it affected my mobility it got my attention. I hope it isn't MS but something less but even if it is, it isn't all that bad in most cases. We have treatments now and it can be very manageable.
I'm 53 now and still walking and working full time. I can't do as much as I used to, but eventually I learned to cope. I learned that getting enough rest, keeping stress levels under control and a healthy lifestyle are very important.
Good luck and keep us posted.
