I've Had A Calf Cramp For About 5 Days Now.

I've had a calf cramp for about 5 days now. Today, just before a 2 mile hike, I jumped over a pile of sticks. When I came down my cramp popped and I was in excruciating pain. I did the hike but it was very difficult. Now, I'm just miserable. Ibuprofen has helped slightly. Any suggestions for management? Thanks!
