Hi i am an 11 year old girl and I get spasm like things in my arms,legs, ankles and feet they hurt so much most of the time it pushes me to tears. it normally happens in my feet and ankles when i go swimming and most of the time the pain makes me get out the pool that can last up to 20 minutes at a time and can make me feel dizzy and sick. I also get them at random moments like yesterday I had one In my hip while sitting at my dinning room table. My question is what is this and should I go to the doctors ???
