 [fah-sik″u-la´shun]

fas·cic·u·la·tion

(fa-sik'yū-lā'shŭn),
1. An arrangement in the form of fasciculi.
2. Involuntary contractions, or twitchings, of groups (fasciculi) of muscle fibers, a coarser form of muscular contraction than fibrillation.

n.
1. A form of involuntary muscular contraction that is more intense than fibrillation, consisting of simultaneous twitching of adjacent groups of muscle fibers.
2. An arrangement of fasciculi.

fasciculation

Brief, involuntary contraction of a small group of muscle fibres, causing visible twitching under the skin. In most cases fasciculation is of no importance but persistent severe fasciculation may imply nerve disease and should be reported.

Patient discussion about fasciculation

Q. Female 57old has fasciculation.Started 3 months ago as a twiching jumping beneath the skin mainly legs & It started with the legs(lower back parts),more so in the right side.Lately also in the hand(mainly arms ,more apparent on the right).There is also a sense of tensed muscles(sometimes painful because of prolonged tension),"pins &needles"and often a sense like a low electric current going through the limbs(mainly legs,sometimes arms).Also sometimes they tend to feel a little numbness and "fall asleep" real easy.She first noticed it only in the morning when she woke up,both legs lower part,back side.About 2 weeks ago it started not to go away,but stay with her all day and night.When she walks it is a lot less noticeable. All the blood tests,vitamins(D,B12,Mg,Na)are OK.TSH(Thyroid)&CK are OK too.Creatine, Calcium,OK

A. Sounds like you have peripheral neuropathy. Have you tried to consult a dorctor (e.g. a neurologist)?

It's a disease of the nerves in the periphery of your body. It may reulst form many things, including diabetes (was your blood glucose measured?) and other diseases.
