Causes of PAINFUL leg cramps?

I didn't read all the posts on here already, but POTASSIUM.

 

I didnt read all the posts either, but just eat a banana. I eat one before each session and never get a cramp when i doo

 

I've had this twice. One there was an upwell in NJ and the water was in the low 60s in mid august, it was terrible I couldnt catch anything, barely able to move.

Last week I was down on friday, While kicking to catch a wave (bodyboarding at the time) a cramp just spiked in my leg and I just couldnt take it

 

i got one during igor....left me a sitting duck

 

no more cramps

I used to get them doing kick sets in the pool and body boarding, I have had them long boarding, usually when inside getting pounded. Swim coaches have told me oxygen, hydration and potassium. Drink lots of water for 2 days before a cramp inducing session, eat your bananas and breath before you need it. I have found that rapid deep breathing can ease a cramp. but here is the best cure...... Tonic Water!!! the quinine in tonic water has some ability to inhibit cramping. I use it regularly now, about 4-6 ounces for a day or 2 before and every day during a several day swell. I mix it with orange juice or just hit it straight up, its kinda gnarliegh but but works.
