@luffing Hi. I read your post and certainly understand where you're coming from. Im also dealing with most of those issues. Between Florida and mi I have dealt with 3 or 4 neurologist plus pain management Drs. I'm 83 and recently, 4 months ago, had a spinal cord stimulator inserted into my back. Abott is the manufacture, but there are others. It does alleviate some of the pain and irritation in my feet. Your Dr has to recommend it and you have to go thru a trial period before it is permanently put in your back. It is not a cure, but it masks the pain messages to your brain. Don't know if you ever thought of this, but if not it is worth looking into
Blessings , Tom
