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.
Most patients with medication-induced hyperprolactinemia will have prolactin levels between 25 and 100 ng/ml (rarely up to 250 ng/ml). If an elevated prolactin level is due to a medication, the level will usually return to normal 3-4 days after the drug is stopped.
