Have you ever experienced pain in the back of your thigh and wondered whether you've injured your hamstring or if the pain is actually coming from your lower back?
It's a common problem, particularly among runners, gym-goers, athletes and people who spend long hours sitting at work.
Although hamstring injuries and lower back problems can produce similar symptoms, their causes and treatments can be quite different.
At Nano Physiotherapy in Hornsby, we help patients identify the source of their pain and develop targeted rehabilitation programs to get them moving comfortably again.
1. Hamstring Injuries: What Do They Feel Like?
The hamstrings are a group of three muscles running along the back of your thigh, connecting your pelvis to your lower leg. They play an important role in walking, running, bending and controlling movement.
Hamstring injuries commonly occur during activities involving sprinting, sudden acceleration, kicking or heavy lifting.
Common signs of a hamstring injury include:
Sudden, sharp pain in the back of the thigh during exercise
Localised tenderness or discomfort when pressing on the muscle
Pain when stretching the hamstring or bending the knee against resistance
Weakness when running, climbing stairs or performing certain exercises
Bruising or swelling following a more significant muscle tear
Not all hamstring problems occur suddenly. Hamstring tendinopathy, particularly near the sitting bone, can develop gradually from repetitive loading.
This may cause persistent discomfort when running, sitting for prolonged periods or performing exercises such as lunges and deadlifts.
2. Lower Back Pain: When the Pain Travels Into Your Leg
Sometimes, pain felt in the hamstring region isn't caused by the hamstring muscle at all.
Problems involving the lumbar spine can produce referred pain into the buttock and back of the thigh. In some cases, irritation of a spinal nerve can also cause symptoms extending below the knee.
Potential causes include:
Lumbar disc irritation or herniation
Irritation of spinal nerve roots, including sciatica
Referred pain from structures in the lower back
Age-related changes in the lumbar spine
Signs your thigh pain may be coming from your back include:
Pain that begins in the lower back or buttock and travels down the leg
Tingling, numbness or burning sensations
Symptoms aggravated by prolonged sitting or certain spinal movements
Pain extending below the knee or into the foot
Weakness associated with nerve irritation
Importantly, you don't always need to experience significant lower back pain for your symptoms to originate from the lumbar spine.
3. How Can Physiotherapy Tell the Difference?
Because symptoms can overlap, identifying the underlying cause is essential before beginning treatment.
At Nano Physiotherapy, our assessment may include:
Lumbar spine assessment: Examining spinal movement and whether certain positions reproduce your symptoms.
Hamstring strength testing: Assessing the muscle and tendon under different loading conditions.
Neurological examination: Checking sensation, reflexes and muscle strength when nerve involvement is suspected.
Functional movement assessment: Looking at movements such as squatting, bending, walking and running.
Clinical history: Understanding how your symptoms began, what aggravates them and how they affect your daily activities.
These findings help us determine whether the problem is muscular, tendon-related, spinal or a combination of factors.
4. How Can Physiotherapy Help?
Treatment depends on the underlying diagnosis, the severity of symptoms and your individual goals.
For hamstring injuries, physiotherapy may involve progressive strengthening, appropriate loading, mobility exercises and a structured return-to-running or sporting program.
For persistent hamstring tendinopathy, we may also consider Shockwave Therapy as an adjunct to a progressive rehabilitation program when clinically appropriate.
For lower back-related pain, treatment may include:
Targeted exercises to improve spinal movement and strength
Manual therapy to help manage pain and movement restrictions
Progressive strengthening of the trunk, hips and lower limbs
Advice on sitting, lifting and activity modification
Nerve-related exercises where appropriate
At Nano Physiotherapy, we also offer MLS Laser Therapy, which may be considered as an adjunct for selected musculoskeletal conditions to help manage pain. These treatments are used alongside active rehabilitation rather than replacing it.
Our goal isn't simply to provide short-term pain relief. It's to address contributing factors, restore function and help reduce the likelihood of recurring problems.
5. When Should You See a Physiotherapist?
If pain in your hamstring, buttock or lower back persists, repeatedly returns during exercise or limits your everyday activities, a physiotherapy assessment can help clarify what's happening.
Early assessment can also help prevent inappropriate stretching or strengthening exercises that may aggravate certain injuries.
New or progressive leg weakness, or persistent numbness, warrants prompt medical assessment. New bladder or bowel dysfunction or numbness around the groin or saddle area requires emergency medical attention.
