3 times over the last week I’ve woken in the night with the worst cramp in my calf ever. It’s that painful that I’m literally squealing in pain and it takes ages to subside, sometimes it’ll go for a few seconds then cramp up again. I feel like I cause it in my sleep because I can feel myself wiggling my legs about and stretching them and then it happens. The muscle in my calf goes all hard and distorted feeling. How do I stop it?! It hurts so bad!
