Hand cramping can occur for many reasons and cause significant discomfort in some people. Often, hand cramps are caused by muscle spasms, which are described as an uncontrollable or involuntary muscle contraction. These spasms or contractions do not allow the muscle to become relaxed and can become excruciating in some cases.
Serum levels of prolactin may increase as a consequence of epileptic seizures. The hormone release is caused by the propagation of epileptic activity, usually from the temporal lobe to the hypothalamic-pituitary axis.
Elevated levels of prolactin decrease the levels of sex hormones â estrogen in women and testosterone in men. The effects of mildly elevated levels of prolactin are much more variable, in women, substantially increasing or decreasing estrogen levels.
