Muscle strains are common injuries—especially for athletes and individuals with jobs that require heavy lifting. Muscle strains in the back cause significant pain and stiffness and may affect your quality of life. How long does it take for a pulled muscle or a muscle strain to heal? It depends on the severity of the injury and how you choose to treat the injury.
Severe muscle injuries, including muscle sprains and strains, limit your range of motion, depending on where the injury occurs. For example, a muscle strain may require time off work or time away from the gym to allow the muscle tissue to heal properly. Conventional muscle strain treatments, as well as natural remedies such as physical therapy, amino acid supplements, massage, and other techniques, can hasten recovery time.
The best advice? Avoid muscle injuries by warming up before exercising and by lifting heavy objects correctly (use those legs!).
Muscle strains occur when muscles are overstretched to the point of tearing muscle fibers. Muscle injuries that involve torn muscle tissue can range from mild to severe. Mild cases, for example, only affect a few of the muscle fibers in the group while the surrounding muscles remain intact. On the other side of the scale, severely strained muscles are torn to the extent that the muscle is unable to function correctly.
According to Harvard Medical School, there are three grades of muscle strains defined by the severity of the damage:
Delayed-Onset Muscle Soreness, or DOMS, presents similarly to a grade 1 muscle strain. DOMS is the result of exercise—or overexercise—and the pain typically appears within 48 hours after exercising and lasts for a few days. Rubbing the muscle and gentle stretching will help the injury heal and relieve pain and tightness.
Muscle strain symptoms depend on the location of the injury and severity. Recognized signs of a muscle strain may include:
Certain areas of the body may present with slightly different symptoms of muscle damage including:
NOTE: An Achilles tendon rupture can cause an audible "pop" like a grade 3 strain, as well as immediate sharp pain in the lower leg and ankle. The Achilles tendon is not a muscle, and if you experience significant pain or the inability to bend your foot or stand on your toes, see your doctor immediately for evaluation and treatment.

If you believe you have a grade 2 or a grade 3 muscle strain, see your sports medicine healthcare team as soon as possible. Your doctor will physically examine the area, testing range of motion, pain, flexibility, and strength. If your symptoms are moderate to severe, X-rays or an MRI may be required to determine the extent of the damage to the muscle so the best treatment for your muscle strain can begin.
If you have a minor muscle strain, your doctor may recommend the R.I.C.E. method:
For minor muscle sprains, your physician will likely suggest an over-the-counter anti-inflammatory medication like ibuprofen and encourage you to begin stretching the muscle after a few days of healing. If the stretching causes pain, give yourself a few extra days to allow the injured muscles to repair.
Grade 2 and grade 3 strains may require prescribed pain relievers and muscle relaxants to relieve discomfort. Severe strains may require a trip to an orthopedic specialist. Depending on the location and severity of the strain, immobilization for a few weeks may be necessary. In severe cases, surgery and physical therapy may be required.
When healing from a sports injury, even a minor muscle strain, it would be wise to consult with a physical therapist who can design a customized recovery and exercise program for you. The last thing you want to do is cause further damage or re-injure your muscle. A sports medicine-minded physical therapist can teach you to exercise properly to spur healing and to create muscles that are strong and flexible, so reinjury of the muscle is less likely.
For all grades of muscle tear damage, taking a full-spectrum amino acid supplement spurs healing of muscle damage when consumed in the days following injury according to a study published in the International Journal of Sport Nutrition and Exercise Metabolism. Researchers from Australia investigated a supplement that contained the nine essential amino acids as well as three nonessential amino acids. Findings support the use of an amino acid supplement 30 minutes prior to working out and immediately upon completion of the workout to reduce muscle soreness and delayed-onset muscle soreness.
Amino acids are required for muscle growth, muscle building, and pain management. If you are looking to heal a muscle strain or other muscle injury—an amino acid supplement is a must. According to an article in the journal Practical Pain Management, amino acids are responsible for three key pain-modulating neurotransmitters, and balanced amino acid supplementation can reduce pain and even reduce the dose of prescription painkillers that are necessary for severe pain. The article further explains that the human body's entire pain-relief system is fueled by amino acids and the hormones they produce.
