CMT is first most noticed when someone develops lower leg weakness, such as foot drop, or foot deformities, including hammertoes and high arches, but signs alone do not lead to diagnosis. [en.wikipedia.org]
- Muscle Cramp
Other features may include hand muscle involvement, hypo/arreflexia, gait disturbances, muscle cramps, toe abnormalities and mild cardiomyopathy. Last updated: 10/1/2018 This table lists symptoms that people with this disease may have. [rarediseases.info.nih.gov]

Treatment
You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]

This disease is the most commonly inherited neurological disorder affecting about one in 2,500 people.[1][2] There are not currently curative treatments for this disorder, with care focused on maintaining function. [en.wikipedia.org]
Prognosis
"[23] Several corrective surgical procedures can be done to improve the physical condition of the affected individuals.[24] Prognosis[edit] The severity of symptoms varies widely even for the same type of CMT. [en.wikipedia.org]

This prevents the synapses from functioning.[12] X linked CMT and Schwann cells[edit] CMT can also be produced by X-linked mutations, and is named X-linked CMT (CMTX). [en.wikipedia.org]
