I'd put a call into my doctor and tell her about your legs. You're obviously "driving yourself crazy" worrying about them. Your heart is okay, evidently, since the EKG came out fine. I don't know what time it is where you are, but leave a message if you need to....Your leg muscles just might be tight from the position you were sitting in--and your worrying might be making it worse. I'm not a medical doctor, but I suspect it's nothing major. But I can understand your concern. Try to do things to keep your mind off it until you can talk to/see the doctor about it. Okay?
