Painless Muscle Cramps

Since high school, my 23 year old brother has had painless muscle cramping that effects only the left side of his body all at the same time.
He saw a doctor in high school who didn't seem too concerned because it didn't happen very often, but now my brother is concerned because it happens
more frequently (sometimes up to three times a day).  The cramps cause his hand to curl up in a strange looking fist--he can manually straighten this out with
his other hand, but it will curl back up when he lets go.  It has gotten to the point now that it interferes with what he is doing.
What would cause such a thing?  He did have a head injury in high school that make him lose his sense of taste and smell.  Are the two things connected?
