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.
During pregnancy prolactin levels increase. After the birth of a baby, a womanâs estrogen and progesterone levels drop and prolactin levels rise. These high levels of prolactin cause milk to âcome inâ or milk production to begin so a baby can be breast fed.
