You sound a lot like me: never really sick, never spent a night in the hospital, athletic(tennis, cycling, golf, skiing, etc,). After a ski fall I experienced lower back pain. After a year and a half, I went to a neurologist who prescribed a cocktail of drugs that really helped. A year later I had a spinal cord stimulator implanted. Along with the meds I was almost pain free for about three years. Then the pain came flooding back for no apparent reason(2021). I had the pain pump implanted in 2023. Has neve given me any relief. I'm in the process of turning it down so I can have it removed. I never had any neuropathic pain until about six months ago. Then it began to creep into my feet, ankles, knees, thighs, and arms. EMG "diagnosed" it as Idiopathic Poly Neuropathy. In other words they don't know the cause. My meds barely touch it. Not sure where to go from here. Hope you can find something to help, I am seventy-seven but feeling a hundred. LOL.
