CMT is often mild and can be left alone but some cases are disabling and need treatment though there is no cure. Step one would be to find out which of the many types of CMT your family has. When you have this key data, ask your GP and if (s)he is unfamiliar with CMT (GP's can't know everything) you could be referred to a neurologist, whose examination may be all that's required, alternatively electrical or genetic testing may be needed. I often see patients who need to know if they've inherited a condition that runs in the family and, at risk of stating the obvious, I need to have full data on the family condition. CMT is a term that covers a large number of inherited peripheral nerve disorders.
