I have been experiencing symptoms over the last three years, and they have gotten progressively worse over the last few months. The most debilitating symptoms have been extreme fatigue, vertigo, and blurred vision. I have also experienced night sweats, cold insensitivity, nausea, vomiting, hand numbness, and general malaise. The symptoms pop up every 3 months or so and last for 1-3 weeks. I spent five days in the hospital recently, and I had a number of scans and tests taken. I have a follow-up appointment with a neurologist in three weeks, but I am hoping to get some thoughts before then. I m happy to share some of my test results if that is helpful. Thank you.
