Running Cramps

So lately when I've been running I've gotten these really bad running cramps. They are extremely bad like I can barely breathe, I can barely run let alone walk. I literally just have to stop where I am in my run and try and walk home as I am wincing with pain. 

And so my runs are looking like this...

No fun! 

I'm wondering if I should see a doctor or just try and run it out. During the Disneyland Half, the cramps lasted for about a mile but I kept running and they went away. But mind you I was crying. So, I'm not sure what I should do. Any ideas? 

QOTD: Have you ever had running cramps? What did you do to help?
