It could. I once was working outside trimming trees and moving all the branches for about 8 hours straight. My biceps both cramped up at the same time and I knew it was from some sort of glycogen problem. I had my wife make me a typical post workout shake (dextrose and whey) since I couldn't move because of the pain. I slammed it really fast and within 5 minutes my cramps were gone. I think part of it was placebo effect, but I never had the problem again.
You might want to eat a sweet potato (or 2) over the next 24 hours and see if that helps.
