Well, I have experience with Type 2 Diabetes, which I "cured" (I know people don't use that word anymore, these days, especially doctors who have been influenced by the pharmaceuticals industry) by means of the paleolithic diet beginning in 2007 and continuing daily to the present. New to me, is the subject of peripheral neuropathy, which I am only beginning to discover in myself. My case involves my hands and only started a couple of weeks ago. So far, it has been confined mainly to my right hand (not unusual, as I am right-handed), but has begun to affect my left hand, as well. I am at the point that this is happening in my right hand two or three times per day, but it is only temporary, lasting an hour or two before returning to normal.
One thing I have noticed is that my long habit of rhythmically drumming my fingers seems to help keep this at bay for a while. Still, there is this numbness I feel that creeps in at some point, usually signaling that I am about to lose control over my fingers. I think that, if I use my finger drumming as a deliberate means of exercise, though, I can ward off the impending loss of dexterity....for a while. Of course, I realize that this is not a remedy for my condition, but, so far, it has helped.
