I am a patient, not a Dr. I understand, no cure for PN. However story doesn't end there. CET treatments exist to reduce the pain. CET may not cure the underlying cause of PN, but CET treatment helped me to generate some new nerve growth which helps in reducing some of the pain while enabling mobility. I walk and drive better. I am doing much much better which improves my life now. Only time, my diet, and exercise will determine blood sugar levels and if/when it gets worse again. Maybe in the future a underlying cure will be found. Until then treatment that helps to reverse or slow nerve damage to any extent is good for me. Medicare covered my CET treatment. I see it as a way to see relief, better then just masking pain.
