The short answer is "concentrated lactic acid." Concentrated lactic acid can get trapped in the spindle in the muscle fiber and can not get out. When this lactic acid gets trapped in the muscle spindle the feedback nerves that are protected in the muscle spindle can only send a weak signal to the cerebellum.
A weak signal from the feedback nerve to the cerebellum tells the cerebellum to contract a muscle. The feedback nerve is trying to send a strong signal which would tell the cerebellum to relax but because the concentrated lactic acid is trapped in the spindle and interfering with the feedback nerve the correct signal can not get to the brain.
As a result the muscle keeps contracting and it never relaxes. The muscles gets stuck in this "bad signal loop" which causes many other problems in the body.
The most common cause of muscle spasms is dehydration. Another common cause is overworking the muscles while working out or doing other activities.
a muscle spasm occurs when the muscles have been tense for a long period of time and then you make a sudden movement and it causes it to spasm. I have suffered with muscle spasm's in my back for about a year now due to a back injury and this is what my doctor has told me, it can be treated with diazapam to relax the muscle's.
Charley horse is a type of muscle spasm that typically occurs in the leg. The muscle spasm causes the muscle to contract by itself and it cannot be relaxed normally.
A spasm is described as a muscle which quickly contracts involuntarily and suddenly. This can be painful. According to the part of the body where the spasm occurs, the cause can stem from various factors. However, in general a spasm will occur if a muscle is overused, therefore running out of energy.

The recommended way of relieving a muscle spasm is a muscle-energy technique called reciprocal inhibition. What you do is have the person with the spasm contract the antagonist muscle(s) related to the ones in spasm. Works like a charm.
Tension in your forearm. Rub it or have someone rub it and it should stop
By a muscle that fails to relax completely resulting in the muscle going into spasm.
What is loss of the normal cervical lordosis consistent with muscle spasm?
He ran so far his leg muscle went into a spasm.
A muscle spasm is the spontaneous recruitment of muscle fibers. The resulting contraction is usually painful, but it typically resolves very quickly.
The word for an involuntary muscle movement is "spasm".
