got a killer cramp in my calf at the wall last night when i was doing quite a dynamic move on one foot. had to drop off the wall and rip off my shoe but i couldn't flex my foot to get rid of the cramp - my calf was locked solid and i couldn't move it for several excrutiating minutes. couldn't use it at all for the rest of the night and just had to campus and moan. it's still all tight and sore when i flex it today and it feels like it could cramp any minute. i'm scared of it happening again.
any advice on preventing/ curing it??
