I've been living with many symptoms for about seven years now and my brain MRI came up clear. My neuro (who I haven't been back to see, nor did he ask for a follow-up) did a EMG and said I have severe carpel tunnel in my right hand and mild in my left. I don't have any pain in my hands, just tingling and a little numbness and weakness. I can still use my hands pretty good just hard to grab things or open boxes at work.  I've had the blurred vision, off balance, slurry speech sometimes,((I feel like I'm drunk sometimes when I'm not). I've had nerve pain, weird sensations, itching, and most recently an onsought of cold sores that have kept recurring for about six months. I have asthma and hypothyroid.
