Have you experienced leg cramps while swimming?

[Liscal74]

Hi. Swimming is my hobby and passion. I feel relaxed after swimming.Now, I cannot swim properly because of leg cramps. My friend who is a physiotherapist in Burlington said that it is caused mainly due to mineral deficiency or by insufficient blood supply to the area.He advised me to consume plenty of water and consume food which is rich in calcium, magnesium, potassium, and sodium. Anyone here had experienced leg cramps while swimming? What do you do to prevent it? Please advise.
