There is still a lot of uncertainty as it's difficult to diagnose something that won't show up on the scans. What we are thinkin now is additional cell death along the perimeter of my spinal cord. There are cells that were killed off in the original injury leading to the need for rehab from wheelchair, to cane, to walking. It's likely that additional cells were damaged and hung on initially, but their life span was shortened. Those cells may now be calling it quits. It's not yet been confirmed. I'm in the process of getting my records to neurologists at University of Washington Medical near Seattle. I want to be sure we get some good eyes on it and look at treatment options.
