A burning sensation in the leg below the knee is usually caused by either a nerve problem or a vein problem. Nerve-related burning feels like tingling, pins-and-needles, or sharp shooting pain. Vein-related burning feels like heaviness, warmth, and swelling that gets worse after standing or at night. The location and timing of your symptoms usually point to the cause, and the treatment is different for each.
At Vein And Knee Pain Vascular Group, we see patients every week who are unsure whether their burning legs are a nerve issue or a vein issue. This guide explains the most common causes, how to tell the difference, and when to see a specialist.
Key Takeaways:
- Burning below the knee is usually nerve-related or vein-related
- Nerve burning feels sharp, tingling, and worse at rest
- Vein burning feels heavy, warm, and worse after standing
- Night-time burning often points to vein pooling or nerve sensitivity
- Persistent symptoms should be evaluated by a specialist
What Causes a Burning Sensation in the Leg?
A burning feeling in the leg can result from multiple underlying conditions. The most common causes include:
- Nerve irritation or damage
- Poor blood circulation
- Vein disease (venous insufficiency)
- Muscle inflammation or fatigue
- Underlying medical conditions
People often describe this as a burning sensation in legs, legs burning sensation at night, or even a hot burning sensation in leg, depending on severity and timing.
Nerve vs Vein Burning: Symptom Comparison at a Glance
| Factor | Nerve-Related Burning | Vein-Related Burning |
|---|---|---|
| Feeling | Tingling, pins-and-needles | Heavy, warm, achy |
| Pain type | Sharp, shooting | Throbbing, burning |
| Location | Usually both legs | Often one leg |
| Timing | Worse at night, at rest | Worse after standing |
| Swelling | Rare | Common |
| Visible veins | No | Often yes |
| Relief | Movement helps | Elevation helps |
| Urgency | See a neurologist | See a vein specialist |
This table is the fastest way to tell the difference. If your burning is tingling and worse at rest, think nerve. If it is heavy and worse after standing, think vein.
Nerve vs Vein Problem: How to Tell the Difference
Understanding whether your symptoms are nerve-related or vein-related is key.
Nerve-Related Burning (Neuropathy)
This type of pain is caused by nerve irritation or damage.
Common symptoms:
- Tingling or pins-and-needles sensation
- Sharp or shooting pain
- Numbness in the lower leg
- Burning sensation in leg muscles or calf
- Symptoms worse at night or when resting
This is often described as a burning sensation in lower leg or burning sensation in legs at night.
Vein-Related Burning (Venous Insufficiency)
Vein problems occur when blood does not flow properly back to the heart.
Common symptoms:
- Aching or heavy legs
- Burning sensation in lower legs
- Swelling in ankles or calves
- Warm or hot feeling in the leg
- Symptoms worsen when lying down or after long periods of standing
Many patients report a burning sensation in legs when lying down or a persistent burning warm sensation in leg. If you are also noticing visible veins alongside the burning, see our guide to DVT vs varicose veins to understand whether the two are related.
Why Does Burning Sensation in Legs Get Worse at Night?
A burning sensation in leg below knee often becomes more noticeable at night due to:
- Reduced movement and circulation
- Increased nerve sensitivity
- Blood pooling in veins
This explains why many people experience legs burning sensation at night or a burning sensation in the legs at night time.

2. Chronic Venous Insufficiency
A major vascular cause where blood flow is impaired.
Symptoms include:
- Burning sensation on legs
