Hi,<br/><br/>Background:<br/><br/>I ran so hard for more than 1 hour last night. And now I feel pain in my both calvs and thighs. <br/><br/>I just feel pain a little bit and if I get myself comfortable, I don't have any pain after all. <br/><br/>I want to know how this status is called. Usually this status lasts for 2 or 3days and goes away.<br/><br/>Thanks.
