Leg Cramp!!!

Ro
Soo i just woke up due to an extremely painful leg cramp. My left calf felt like it was being bitten off by a shark! its 5:09 am and the pain has gone away..but now i feel like my calf and foot is sore, and that it might happen again if i move it wrong, what can i do relieve the pain after the cramp? i read on google what to do when the cramp is happening but what do i do now that i feel sore and achy and scared to move it because im afraid it'll happen again
