The easiest way to tell femoral nerve pain from sciatica is by where it hurts. Sciatica spreads from the buttock along the back or side of the leg, often below the knee and down to the foot, and usually involves the L5–S1 nerve roots. Femoral nerve pain affects the front of the thigh, sometimes the inner side of the shin, and involves the higher L2–L4 nerve roots. Femoral nerve pain is much less common.
Below you will find a table comparing the two conditions, the symptoms that require an urgent visit to a doctor, three gentle exercises with dosage, and a description of what therapy looks like at the clinic in Rydułtowy and in the patient’s home.
In brief
- Sciatica is pain at the back of the leg, usually from the L4–S1 segment; femoral nerve pain is pain at the front of the thigh, from the L2–L4 segment.
- Numbness in the groin area, problems passing urine or stools and progressive leg weakness are a reason for urgent medical help (A&E (SOR), 112).
- In most people nerve root pain in the leg eases within a few weeks of conservative treatment.
- A physiotherapy consultation at the clinic costs PLN 180; the clinic sees private patients only, not covered by NFZ (the Polish public health fund), Mon–Fri 7:00–20:00.
- Home physiotherapy: approximately PLN 200 for up to 5 km, then + PLN 2/km, up to 15 km from Rydułtowy.

How does femoral nerve pain differ from sciatica?
Both are radicular pain, i.e. pain caused by irritation of a nerve root in the lumbar spine, most often by a herniated intervertebral disc or narrowing of the spinal canal. They differ in the level of the spine and the nerve involved: sciatica affects the sciatic nerve (L4–S3), and femoral nerve pain affects the femoral nerve (L2–L4). That is why the pain follows a different path down the leg.
Telling them apart is usually difficult when the pain is diffuse or involves the hip and groin. The table below compares the same criteria for both types. It is an aid for talking to a physiotherapist or doctor, not a tool for diagnosing yourself.
| Criterion | Sciatica | Femoral nerve pain |
|---|---|---|
| Nerve roots | most often L5 and S1 | L2, L3, L4 |
| Where it hurts | buttock, back or side of the thigh, calf, often the foot | groin, front of the thigh, sometimes the inner side of the shin |
| Examination test | straight leg raise test (Lasègue’s test) | femoral nerve stretch test (bending the knee while lying on your front) |
| Possible weakness | big toe extensors, calf muscles (rising onto your toes) | quadriceps (climbing stairs, standing up) |
| Reflex | the ankle (Achilles) reflex may be reduced | the knee reflex may be reduced |
| What makes the pain worse | sitting, bending forward, coughing | straightening the hip, lying on your front, standing for a long time |
| Conservative treatment | activity, exercise, manual therapy, McKenzie method | activity, exercise, manual therapy, more careful choice of positions |
| Consultation at the clinic | PLN 180 | PLN 180 |
How to recognise sciatica?
Sciatica is pain that spreads from the lower back or buttock down the back or side of the leg, usually below the knee. It is often accompanied by numbness or tingling in the foot, and the leg pain may be stronger than the lower back pain. Symptoms get worse when sitting, bending forward, coughing and sneezing.
A typical patient describes an “electric shock” or “pulling” from the buttock to the calf or to the little toe or big toe. The doctor or physiotherapist then checks whether raising the straight leg while lying on your back reproduces the leg pain, and assesses muscle strength, sensation and reflexes. We write more about what to do in the first few days in our article sciatica — what to do and when to see a physiotherapist.
How to recognise femoral nerve pain?
Femoral nerve pain is pain that spreads from the lumbar spine to the groin and the front of the thigh, sometimes to the knee and the inner side of the shin. It may be accompanied by weakness of the quadriceps, which makes it harder to climb stairs or get up from a low chair. The pain often gets worse when you lean your upper body backwards.
Femoral nerve pain more often affects older people, in whom the cause may be narrowing of the spinal canal or of the openings between the vertebrae. During the examination the physiotherapist has the patient lie on their front and bends their knee. Familiar pain at the front of the thigh suggests irritation of the femoral nerve, but the result is always assessed together with the medical history and a neurological examination.
Is pain at the front of the thigh always femoral nerve pain?
No. Pain at the front of the thigh can also be caused by hip joint disease, muscle overload, compression of the lateral cutaneous nerve of the thigh (meralgia paresthetica), an inguinal hernia, and in people with diabetes, neuropathy. Hip pain usually gets worse when the joint rotates and when walking, while meralgia causes burning on the outer side of the thigh without muscle weakness.
That is why the first step is not choosing exercises from the internet, but an examination. At the consultation the physiotherapist checks the mobility of the hip and spine, nerve tests and muscle strength. If the picture does not fit nerve root pain or worrying symptoms appear, they refer the patient to a doctor. We describe how to choose a specialist in our article back pain: physiotherapist, orthopaedist or neurologist.
When should you see a doctor first about nerve root pain?
Urgent medical help is needed for nerve root pain with numbness in the groin or inner thighs, new problems passing urine or stools, rapidly increasing leg weakness or foot drop. You should also see a doctor if the pain follows an injury, with fever, with night pain and weight loss, and if you have a history of cancer.
Red flags:
- Numbness in the groin, buttocks or inner thighs (“saddle” numbness) — go to A&E (SOR) or call 112 immediately (suspected cauda equina syndrome).
- Urinary retention, incontinence of urine or stools, or erectile problems that appeared suddenly — go to A&E (SOR) immediately.
- Rapidly increasing leg weakness, foot drop, the knee “giving way”.
- Pain after a fall or injury, especially in people with osteoporosis.
- Fever, chills, unintentional weight loss, pain that gets worse at night and at rest.
- A history of cancer, long-term use of steroids, lowered immunity.
- Pain in both legs at the same time, or symptoms that get worse day by day despite rest.
With neurological symptoms, the doctor may refer you to a neurologist. In the Recommended specialists section, the clinic recommends a neurologist, Radosław Bienek, MD, PhD.
Which exercises are safe with nerve root pain?
In the first few days the safest options are a calm walk within the limits of your pain, changing position every half hour or so, and gentle breathing and movement exercises in relieved positions. Forcefully stretching the nerve is not a good idea. A physiotherapist chooses a programme for your specific condition after an examination, because femoral nerve pain and sciatica are often eased by different positions.
- Walking within the limits of your pain. 3–4 times a day for 5–10 minutes, at a steady pace, on flat ground. Add a few minutes every 2–3 days if the leg pain does not get worse.
- Diaphragmatic breathing lying on your back with your legs on a chair (hips and knees bent at a right angle). Breathe in through your nose so that your belly rises, then breathe out slowly through your mouth. 2 sets of 8 breaths, 2–3 times a day.
- Pelvic tilts lying on your back with your knees bent. Gently press your lower back into the floor and relax. 10 repetitions, 2 sets, twice a day, within a pain-free range.
If the pain gets worse or spreads, stop the exercise and consult a physiotherapist.
How does a physiotherapist treat femoral nerve pain and sciatica?
Treatment starts with a consultation (PLN 180), during which the physiotherapist takes a medical history, examines mobility, strength, sensation and reflexes and rules out red flags. They then choose exercises and positions that reduce the pain, give advice on everyday activity and, if needed, use manual therapy or the McKenzie method. The number of visits is decided individually.
At the “W zdrowym ciele” clinic we use, among other things, assessment and exercises based on the McKenzie method, manual therapy and Cyriax orthopaedic medicine. Physical therapy modalities such as TECAR can be a complement, but they do not replace exercise and education.

The MRI result alone does not determine the treatment, because disc changes are often seen in people without pain too.
Summary
Sciatica hurts at the back of the leg and usually involves the L5–S1 nerve roots, while femoral nerve pain hurts at the front of the thigh and involves the L2–L4 roots. “Saddle” symptoms, bladder problems and increasing leg weakness require urgent medical help. In other cases the starting point is a physiotherapy consultation at the clinic in Rydułtowy for PLN 180 or a home visit, approximately PLN 200 for up to 5 km.
Frequently asked questions
How long does femoral nerve pain last?
How long femoral nerve pain lasts varies and depends on the cause, the patient’s age and their activity. In many people the symptoms ease considerably within a few weeks of conservative treatment, but they can also become long-lasting. If the pain does not ease after a few weeks or muscle weakness appears, you need to be reassessed by a doctor.
Can I walk with nerve root pain in the leg?
Yes, if there are no warning signs it is recommended to stay moderately active, including short walks within the limits of your pain. Lying in bed for a long time does not speed up recovery. Stop walking if the leg pain gets clearly worse, and discuss how active you can be with a physiotherapist during the consultation.
Is femoral nerve pain more serious than sciatica?
Femoral nerve pain is not more serious by definition, but it more often affects older people and higher nerve roots, so it needs careful diagnosis. Pain at the front of the thigh can also come from the hip joint or from outside the spine. How serious the problem is depends on the neurological symptoms, not on the name of the condition.
Do I need an MRI scan for nerve root pain in the leg?
Not always. Guidelines recommend imaging mainly when there are warning signs, worsening neurological deficits or when surgery is being considered. In most people with nerve root pain and no red flags, conservative treatment starts without an MRI scan. The decision to refer you for a scan is made by your doctor.
Do I need a referral for a visit with nerve root pain in the leg?
For a private visit at the “W zdrowym ciele” clinic a referral from a doctor is not required. It is, however, worth bringing your medical records, imaging results and a list of your medicines. If symptoms that need a medical diagnosis appear during the examination, the physiotherapist will tell you and advise which specialist to see.
Does the clinic treat patients with nerve root pain under the NFZ?
No. The “W zdrowym ciele” clinic in Rydułtowy has no contract with the NFZ and sees private patients only. A physiotherapy consultation costs PLN 180, and manual therapy PLN 180. The clinic is open Monday to Friday, 7:00–20:00, and you can book a visit through Booksy or by phone.
