I am an otherwise healthy, 80 year old physician. I am not diabetic. Numbness began in my left toes and gradually spread over my feet and up my legs. There is some burning of the feet, but not too severe. At times I can barely identify my own feet due to numbness. I have had a thorough and comprehensive neurological work-up. All my blood panels are normal. There has been no real answer nor a treatment. I wish to know the cause and to know if anyone has had cold laser therapy and has it worked?? Thank you. BHL
