Hi. For A Number Of Months I Have Had A

Hi. For a number of months I have had a slight numbness in the tips of my fingers of my left hand. I am otherwise extremely fit 60 year old male, cycling for 25 kilometers 5 days out of 7. A chiropractor has said that my C5 vertebrae is damaged based on an X-ray he had taken - this may have been caused from a fall from a roof in 1981 or by a power pole landing on my head when I was 16. Thoughts.
