what causes upper leg muscle twitching
Common Causes of Leg Twitching. Leg twitching is an aggravation of the muscles caused by very small contractions within the muscle. Electronic impulses sent through nerves in the body tell the muscles to contract.These contractions are involuntary and unexpected, causing the patient to experience uncomfortable sensations that cannot be controlled.eg Twitching is often diagnosed as Restless Leg syndrome (RLS). Uncomfortable sensations in the legs, especially during rest cause the patient to voluntarily move their legs to remove the sensations. Involuntary movements of the legs during rest may be a sign of Periodic Limb Movement Disorder (PLMD).
