Myokymia
Myokymia consists of wave-form or “serpent-like” movements of the skin due to contraction of thin cutaneous muscles. Myokymia may also be associated with neuromyotonia which is characterized by repetitive contraction of muscle fibers secondary to hyperexcitability of peripheral neurons. Muscles affected may be focal to one limb or diffusely affecting all limbs.
Myokymia may also be associated with post-radiation therapy at the site of therapy.
