Hi.. My husband also had this problem. He thought he had pulled a muscle it lasted a week before he agreed to go to a Dr. and yes it was a blood clot.He went on coumidin for a while and then stopped it. A week later he developed a blood clot in the other leg. So now he is on Coumidin the rest of his life. Please just have this checked out because you never know. sincerely debbie
