Burning sensation down the leg
Also Known As: Sciatica, sciatic nerve pain, femoral nerve pain, obturator nerve pain, lumbar radiculopathy, nerve referred leg pain
A burning, electric, shooting, or aching sensation that travels from the glutes, through the back of the thigh, and sometimes into the calf or foot. This can also occur through the front of the hip, down the front of the thigh, or in the inner thigh. Can be constant or triggered by sitting, bending, running, or specific positions. May accompany low back stiffness or hip tightness.
Possible conditions related to Burning sensation down the leg
Common Causes
Lumbar disc irritation or herniation compressing nerve roots at L4–S1
Piriformis or deep hip rotator tension compressing the sciatic nerve in the gluteal region
Prolonged sitting causing sustained nerve compression
Poor hip mobility or lumbar control during running loading the nerve repeatedly
Tight hamstrings increasing sciatic tension during gait
Sacroiliac joint dysfunction altering nerve mobility
Did You Know?
The sciatic nerve is the longest nerve in the body and it can be irritated at multiple levels — the spine, deep hip, hamstring tunnel, or behind the knee. Finding where the tension is coming from changes the entire treatment approach, which is why a movement assessment is more useful than just stretching the hamstring and hoping it resolves.
How Zenith Can Help
At Zenith in Eugene, our DPTs assess nerve mobility, nerve irritability, lumbar mechanics, hip control, and the specific pattern of your symptoms to locate the source of irritation. We also test sensation, strength, and reflexes to ensure that the nerve irritation is not something that needs further evaluation or imaging. We use manual therapy for joint and soft tissue mobility, targeted nerve flossing and desensitization, and progressive loading to restore full function. We don’t just treat the leg — we address the root cause and upstream mechanics driving the nerve tension.
Next Steps
Don’t wait on this one. Nerve symptoms that travel below the knee, are present at rest, or include weakness or bowel/bladder changes need prompt evaluation and potentially a higher level of intervention. Book a PT session — early intervention avoids chronicity and keeps you on the road. Our PTs are trained in diagnosing whether you are appropriate for conservative care or should seek imaging and surgical consultation.
Extended trail runs on technical terrain like Ridgeline or Mt. Pisgah can aggravate sciatic symptoms from sustained hip flexion and trunk loading, especially if you’re already dealing with lumbar stiffness. If the burning increases on descents or after sitting in a car post-long run, those are useful patterns to share with your PT. We see this often with people who have stationary jobs and active hobbies.
