Hi, no he doesn't have that or any bone issues. The SFN is his biggest issue and it took 2 years to get that diagnosis. He was diagnosed with MGUS after getting covid, shingles, then covid again in early 2023. He had the covid vaccine and the shingrix shot, but still got both and had a hard time shaking them. Then the tingling started in his knees and has slowly spread in both directions. I hope you can find some relief, I know treatment options are so limited.
