Thanks for the welcome.
I was given an mri in December for weakness in my tongue,jaw area while chewing. My arms have also become sooo tired while hanging up clothes or washing dishes or even some times just walking. They have been going on for over a year. I've had two ncv test and also two emg test that were normal. The mri showed moderate diffuse cerebellar atrophy. My neurologist dx spinocerebellar ataxia. I had been having leg problems for 2+ years. I had been told it was the result from my lower back problems. I have severe narrowing at two different level of my lowere spine. My legs tingle and burn 24/7. I also have strange vibrations , like a cell phone is going off in my thigh sometimes. I now am waiting on my genetic test results to see what type of spinocerebellar ataxia it is. I'm worried but am glad to have a dx after all this time.
Sorry for the long post
