i am having severe spasms in my feet and legs that are worse at night. my spasms are so severe that the tendons in my feet and up my legs raise up and cause my foot to draw to the side so bad it feels like my ankles will dislocate. it draws my toes up or down. it is accompanied by cramps and twitchy spasms in the muscles of my calfs and legs and knees. is this normal?
