My father developed severe fatigue/weakness/lack of coordination and the neurologist recommended that the Ommaya reservoir be removed. It was and he was "fine" for a couple of years but now has developed the same problem, though now in "spells" that have landed him in the hospital at least three times, going through a battery of tests, CT scan, EEG, chest x-ray, lumbar tap, all of which are negative.
Any ideas as to what this could be? He has an extensive history including bone marrow transplant and chemo but is supposedly cancer-free right now. Need help. No one has any ideas about what could be wrong and how to "fix" it.
