Welcome to the club house Jayne. (thats my maiden name, spelled the same too!) I am sorry that you find the need to seek us out, but happy we are here to help.
There are more than 100 diseses that can mimic MS. A lot can be ruled out with simple blood tests, and others are more complicated. Many have been diagnosed without a single lesion, and a negative spinal tap. Others have had to wait till they are riddled with them. This disease is so frustrating. I am sorry to hear that your mother suffers from it too. I just wanna slap the crap out of this stupid disease.
I think you will find loads of nice folks to lean on, cry on, and cheerlead with here.
Pull up a chair.
