Healing time from an injury will vary from one person to another, depending on their body’s natural healing process and how mild or severe the injury was, as well as which muscle was injured. In the case of a hamstring injury, healing time can be a matter of a few days for very mild strained hamstrings, up to 18 months for severe hamstring injuries. In most cases, a hamstring injury can have an active person sidelined for several weeks while the muscle heals. People with a hamstring injury will want to ensure it is properly healed and steps are taken to avoid reinjuring the area as the chances of injuring the hamstring increase once it has been injured once. The specialists at The Orthopedic Group will examine the area to determine the extent of the injury and provide you with a treatment plan to heal the pulled muscle, as well as a preventative plan to avoid reinjury in the future.
