I was referred to Dr. Van Fossan to try to figure out why I have numbness/tightness in my right hand. .. figured carpal tunnel, but these are not the usual fingers affected by carpal tunnel issues. Turned out to be peripheral neuropathy, closely associated with diabetes — which had NOT been diagnosed by any other doctor, even though lots of blood tests have been done on me over the last year. I found Dr. Van Fossan to be delightfully old fashioned, with no flashy new equipment. .. just old school techniques and an excellent mind.
