I'm so sorry to hear about your wife, hon. I don't want to guess on what this could be, but I think you need to find a neurologist there and have her evaluated sooner rather than later.
Indo is a doctor/surgeon and is a pretty cool guy. Maybe he will be able to help steer you in the right direction. If you don't see him logged onto the board, shoot him a PM.
I'll definitely keep your wife in my prayers and hope that someone can help her.
