Why do my calves muscles hurt so much?!

Why do my calves muscles hurt so much?

I woke up really late today. (Litke 1:15 pm) but I got out of bed. (I actually fell asleep on the couch) As soon as i put my feet on the floor when i stood up. I had to bend my knee and limp because when I stood up I have this ache in both of my calves hurt. I felt like if i kept walking i would get a charlie horse. I put heat on then and now I have cold ice packs on them. It doesn't hurt as much when I walk but walking in heels makes it not hurt as much. Why do my calves muscles hurt. Did i pull the muscle or something.

They may have just gotten cramped. Stretch them out gently, try some icy hot, or soak them in watm water. Eat bananas, the potassium can help prevent cramps (they tell you to do it for kids that are learning to walk).
