I was sound asleep thirty minutes ago. I awoke to crazy pain that I was confused about [it takes me awhile to awake usually]. After minutes of intense pain from my shin down to my ankle, I read up about muscle spasms. Doctors have suspected triggors and I may fall into most of the categories, but I hope it never happens again! At the end of one of the articles the quoted doctor said, "In essence, it's just a fact of life, it's just one of those things you have to learn to live with." Ummmm.... no thank you! I cannot imagine learning to live with this! AHHHH! What muscles cramps have you had?
