No. The initial healing occurs quite quickly, usually within a week. Think of a clean cut; it only takes a few days for a scar to form. Scar tissue that forms around a joint or in a muscle may shorten as it matures. When you move, the scar is pulled, which is painful. Unless you recover full movement and strength, your injury will continue to hurt. So it is not that you haven't healed, it's that you haven't healed effectively. The solution is to perform the correct exercises to promote healthy, flexible scar tissue.
