Hamstring injuries can stop you in your tracks, whether you are a competitive athlete or someone who stays active on weekends. These strains and tears in the muscles at the back of your thigh need a clear, structured recovery plan.
Dr. Reza Jazayeri, a double board-certified orthopedic surgeon with a sports medicine fellowship from the Kerlan-Jobe Orthopaedic Clinic in Los Angeles, brings over 15 years of experience treating these injuries. His approach combines advanced surgical techniques with biologic augmentation and metabolic optimization. He sees patients at his Beverly Hills, Westlake Village, and Orange offices, offering non-surgical options whenever possible.
Symptoms Of Hamstring Injuries To Recognize
A sudden sharp pain in the back of your thigh during activity is the most common sign of a hamstring injury. You might feel a popping or tearing sensation at the moment of injury. Swelling and tenderness often develop within a few hours.
Bruising can appear below the injury site as blood tracks downward. Walking may become difficult, and straightening your leg fully can feel tight or painful.
The severity ranges from mild tightness to an inability to bear weight. Recognizing these symptoms early and getting a proper evaluation helps you avoid making the injury worse by pushing through the pain.
Initial Care Steps For Hamstring Injuries
Start with rest and protection right after a hamstring injury. Stop the activity that caused the pain and avoid stretching the muscle aggressively in the first 48 hours. Apply ice wrapped in a cloth for 15 to 20 minutes at a time, several times a day.
A compression wrap can help control swelling, and elevating the leg above heart level when sitting or lying down supports drainage. Over-the-counter anti-inflammatory medication may help with pain, but check with your doctor first. These early steps set the stage for healing, but they are not a substitute for a full evaluation if pain persists or walking remains difficult.


Role Of Physical Therapy In Recovery
Physical therapy is a central part of hamstring injury recovery. A structured program restores strength, flexibility, and normal movement patterns in a gradual, controlled way. Early sessions focus on gentle range-of-motion work and reducing muscle guarding.
As healing progresses, you move into eccentric strengthening exercises, which load the muscle as it lengthens. This phase is critical because weak eccentric control is a known risk factor for re-injury.
Your therapist also addresses any hip or core weaknesses that may have contributed to the strain. The goal is not just to heal but to return to your sport or daily activities with better mechanics than before.
Innovative Treatments For Hamstring Injuries
For patients who need more than standard rehabilitation, several advanced options are available. Platelet-rich plasma therapy uses a concentration of your own blood platelets to support the body’s natural healing signals in the injured tissue. Dr. Jaz incorporates orthobiologics, including PRP and stem cell augmentation, into treatment plans when appropriate.
His Bio-Fertilization Technique combines biologic augmentation with intraosseous modulation and metabolic optimization. This framework addresses healing at multiple levels.
Preoperative lab testing for vitamin D, inflammatory markers, and muscle status is a standard part of his protocol, backed by his own peer-reviewed research. These methods aim to create a better environment for tissue repair.
Preventive Measures For Hamstring Injuries
Preventing a repeat hamstring injury starts with grasp why the first one happened. A proper warm-up that includes dynamic movements like leg swings and walking lunges prepares the muscle for activity. Eccentric strengthening exercises, such as Nordic hamstring curls, have strong evidence for reducing injury risk.
Maintaining flexibility through regular stretching, especially after exercise, keeps the muscle from becoming overly tight. Do not ignore fatigue. Hamstring injuries often occur late in a workout or game when form breaks down.
Addressing muscle imbalances between the quadriceps and hamstrings also lowers your risk. Consistent, year-round conditioning matters more than a quick pre-season tune-up.
Benefits Of Aquatic Therapy For Recovery
Aquatic therapy offers a low-impact environment for early-stage hamstring rehabilitation. The buoyancy of water reduces the load on the healing muscle, allowing you to move with less pain and less risk of re-injury. Walking, gentle kicking, and range-of-motion exercises in the pool help maintain cardiovascular fitness while the tissue repairs.
Hydrostatic pressure can also help control swelling. As you progress, the water’s resistance provides a safe way to begin strengthening without the full stress of land-based exercises. For patients in Los Angeles who want to stay active during recovery, aquatic therapy bridges the gap between rest and a full return to training.


Importance Of Strengthening Exercises For Hamstrings
Strengthening the hamstrings is about more than just the muscle itself. A complete program includes the glutes, core, and hip stabilizers because these muscle groups work together during running, jumping, and cutting movements. Eccentric exercises like the Nordic hamstring curl specifically target the phase of muscle action where strains most often occur.
Progressive loading, where resistance increases gradually over weeks, rebuilds the muscle’s capacity to handle force. Single-leg exercises such as Romanian deadlifts also improve balance and control.
Dr. Jazayeri’s prehabilitation approach includes structured pre-surgical conditioning, and the same principle applies to non-surgical recovery. Building strength before returning to full activity reduces the chance of setbacks.
Frequently Asked Questions About Hamstring Injuries
-
The most common symptom is a sudden sharp pain in the back of your thigh during activity. You may also experience swelling, bruising, and difficulty walking or straightening your leg.
-
Start with rest and avoid activities that cause pain. Applying ice for 15 to 20 minutes several times a day can help reduce swelling, and using a compression wrap may also be beneficial.
-
Physical therapy is crucial for restoring strength and flexibility after a hamstring injury. A therapist will guide you through exercises that help regain normal movement patterns and prevent re-injury.
-
Yes, treatments like platelet-rich plasma (PRP) therapy and biologic augmentation can support healing. These methods are designed to enhance recovery and may be considered if standard rehabilitation is not enough.
-
Proper warm-up routines and eccentric strengthening exercises are key to preventing injuries. Maintaining flexibility and addressing muscle imbalances can also significantly reduce your risk of future hamstring strains.
