Hi, Mary!

Welcome to NeuroTalk!
Much of what you describe is familiar to me in terms of MS, but many other neurological conditions are similar. I was in your shoes many years ago and was determined to get an answer. From my perspective, it's better to fight your way through and know what it is so that you can learn to treat it and get on with life.
It's terribly frustrating, I know, but not knowing was worse for me. I hope that you will pursue an answer and that it is not MS. MS sucks.
