Hi there
I have similar symptoms and have had nearly every blood test under the sun over the last month. I am waiting on having an MRI on the 3rd Sep.
I will keep you posted as we seem to have similar symptoms, mine come and go with extreme spasms in arms and legs and I constantly feel twitchy. Hard to work full time and be mum with all this going on and no answers as yet

Mine seem to get worse upon exersion or stress, do yours?
Hope you feel better soon
Shae
