A charlie horse.....: Large muscles use a lot of energy to do work, and this is supplied by blood. If the supply is not adequate their can be painful spasm; and if metabolites from heavy activity are not removed there can be spasm. Other causes can be a trapped nerve root irritating the muscle. Some people have greater likelihood of spasm due to underlying genetic causes.
