Unfortunately I think that this kind of stuff is not that uncommon. Motivation is either money (most likely) or the belief that in pain medicine we keep reaching into the tool bag until we provide relief or the tool bag is empty.
I think there is wisdom in what SLobel frequently states. “ I can treat what I can diagnose” or something along those lines. I think most on this forum are similarly minded. Visiting other pain doc forums I see a lot of nonspecific pain problems treated with nerve block, neurolysis, SCS, DRG, peripheral stim, IT opioids and then IT Prialt. DBS would be included if a hospital would allow a pain doc to do it. I have to wonder when the treatment becomes worse than the disease or in these cases just a symptom without a disease. I’m sure the docs performing these procedures would argue that one should be availing oneself of all that pain medicine has to offer to alleviate pain and that not doing so is being a wimp.,
