Hi @opai - definitely in my prayers your son has some relief from the cold laser therapy. I was diagnosed with small fiber neuropathy in both feet in August 2023. On a journey to figure out how to effectively live with the disease. One step I took in 2023 was to receive cold laser therapy and electrical stimulation of both feet two times a week for nine weeks. Believe it did help but not dramatic enough to continue with the treatment. Not covered by Medicare and very expensive. Would definitely continue the treatment if more affordable and dramatic, long lasting improvement. Again, prayers for you and your son.
