Hi,

I started having double vision approximately a week and a half ago. They've ruled out stroke, MS and have decided that it's either MG (myasthenia gravis) or possibly a weak muscle. My neuro-opthamologist thinks that it's MG even though my initial blood tests were negative. I've got a temporary prism in place to help with the double vision and I'm scheduled for a nerve conduction study next week to diagnosis if it is MG or not.

Has anyone else ever had the initial blood work for MG come back negative and actually ended up with a positive dx? Also, has anyone ever had it spread from having double vision to issues with other muscles in their body? I'm new to all this so I appreciate any feedback.

Thanks!
