Hamslice, you obviously have much more experience dealing with the VA than I have and certainly have much more understanding of the intricacies of the age-old, sacred, self-protecting, selfish roles the VA has, but, just like the IRS, FDA, DOD, and most US government agencies, including Congress, they devise rules and laws which focus on their self interests first.
I should have started this reply (or probably not even started it at all), by explaining that I am writing this at 3:17 in morning. I cannot sleep because of leg pain caused by some anomaly in my nerve system,an unsolvable medical problem. I have 5 TENS devices I purchased with my own money, but they cannot operate for more than an hour due to an FDA rule,law, edict or whatever they call it. If the TENS manufacturers increased the operating time, the would suffer financially. The FDA know I learned, over 25 years ago,
