A sudden, involuntary contraction of a muscle, a group of muscles or other parts of the body, such as a hollow organ or an orifice is known as a spasm. It is usually harmless, and is set off by irregular stimulation of the nerve, or unusual movement in the muscle itself. A muscle spasm can occasionally indicate an underlying, undiagnosed disorder.
HOW IS MUSCLE SPASM DIAGNOSED?
There are several kinds of muscle spasms, such as hypertonic, and myoclonus.
