Re: 18 months of hell, need answers!
There are a few things that run through my mind when I read your husband's symptoms but he really needs a good work up from a neurologists that specializes in brain issues. I know here in the Pacific NW there is a clinic called "Brain Matters" I don't know if there is something similar in your area in CA. There is definitely something that is going on that seems some Dr. would take him under his wing to find out what it is.
I have had many of his symptoms and I have heard of others with MS having some of the ones I haven't had but there are a few things that I haven't heard being related to MS.
I wish the best for you two and hope you can find an answer.
