Hi. I'm a 50 year old male, recently diagnosed with chronic aseptic meningitis. It started about 18 months ago with a strange sensation, like water sloshing around in my head. No other symptoms / problems - no head 'pain' for example. Two MRI scans, blood tests, and lumbar puncture, and still no cause identified. The sensation remains and has not changed since it began. I'm working, driving etc without any problems. My consultant is sending me to someone else for a second opinion.
Does anyone have any experience or knowledge of what is going on here, or is it something I'm going to have to live with?
