Hi Rossy and welcome to NeuroTalk!

I'd be afraid to speculate as to what you're dealing with because those symptoms fit so many different conditions. There are several that come to mind.
My suggestion would be to see a Neurologist. If you've already seen one and aren't satisfied with their treatment then go to another one. You'll probably have to have some blood work and various testing done to rule out certain conditions before they can diagnose you by a process of elimination.
Take a look around at the different forums and read some of the posts. I hope you can find a doctor who'll work with you until you get to the bottom of what's causing your symptoms.
