I suddenly developed some symptom that are raising some major questions for me. I took all my meds as I do every night. While laying in bed trying to sleep I was woke up by shooting nerve type feeling on my whole left side. Mainly my arm and leg. It made me very uncomfortable so I got up to try and walk it out and noticed when I stood up I almost felt drunk (was only drinking water) and I couldnt see very well..everything was blured. This went on for about an hour or so then I was finally able to fall asleep for the night. I seemed okay today and it started to happen again about an hour ago but not as sever. I have noticed my left arm seems heavy and I have a constant ringing in my ears. What could cause this?
