I don't entirely agree. unproven therapy, for unproven condition. and expensive and has risks for patient. there are a lot of conditions for axial back pain that will not be improved or impacted by stimulation.
in addition, it is often difficult to parse out what degree of pain is in part psychological, and stim trials and other advanced interventional options will do nothing to address these conditions.
what gets me is that it is not okay to say "I cant help you." we can always help, but its not always through a needle or an opioid prescription. in truth, if I used your logic, then I would find it hard to refuse to prescribe opioids to, say, fibromyalgia because "it might offer some relief" theory...
