Most patients reach my clinic 5–10 years after their first symptoms began — by which time damage has progressed from cosmetic concern to skin ulcers, brown discolouration, or blood clots. The single most important thing you can do is recognise varicose veins symptoms early and act before complications develop.
Below is the definitive symptom guide based on 18 years of vascular practice and the international CEAP classification used by every vein doctor worldwide.
1. The very first sign: leg heaviness by evening
Almost every patient describes the same first symptom: "my legs feel like lead by 6-7 PM." The heaviness is worse after long standing or sitting, and improves dramatically after lying down or sleeping.
This happens because diseased one-way vein valves leak, causing venous blood to pool in the lower leg under gravity. By evening, your leg has up to 800 ml extra blood than it should — hence the "lead" feeling.
Action: if you have this for more than 2 weeks, get a Doppler ultrasound. Read more: early signs of varicose veins.
2. Visible bulging or twisted veins on legs
The classic sign — rope-like, bluish-purple, bulging veins on calves, thighs, or behind the knees. Often more visible after a hot shower, exercise, or long standing.
Differentiate from harmless spider veins: spider veins are thin red/blue web-like lines flush with skin. Varicose veins are raised, bulging, and > 3 mm wide.
3. Aching or throbbing pain in legs
Different from muscle pain. Varicose vein pain is:
- Dull, aching, throbbing — not sharp
- Worse at end of day, better in the morning
- Worse after standing/sitting still, better after walking
- Relieved by lying down with legs elevated

4. Ankle and foot swelling (oedema)
Swelling around the ankles by evening, with sock-marks deeply imprinted on the skin, is a key C3 stage symptom. The swelling reduces overnight and reappears next evening.
If swelling is in only one leg and is sudden + warm + red, it could be DVT (deep vein thrombosis) — a medical emergency. See a doctor the same day.
5. Itching, burning, or tingling over the veins
Persistent itching directly over the bulging veins, especially around the ankles, is called venous eczema. Patients often scratch themselves into open sores. This is a sign that disease has progressed to C4 stage and intervention is now strongly recommended.
See: itching in veins — treatment guide.
6. Night-time leg cramps (especially calves)
Sudden, painful calf or foot cramps at 2–4 AM that wake you from sleep — extremely common in varicose vein patients. Often misdiagnosed as "calcium deficiency" or "magnesium deficiency."
Mechanism: pooled deoxygenated venous blood + electrolyte shifts during sleep. Resolves dramatically once the underlying refluxing vein is treated.
7. Restless legs syndrome
Uncomfortable urge to move legs while resting, especially at night. Up to 35% of moderate varicose vein patients also have restless legs. After endovenous laser/RFA, restless legs symptoms improve in 70-80% of patients.
8. Skin colour changes — brown / black patches
Brownish or blackish discolouration around the inner ankles is called haemosiderin staining — caused by red blood cells leaking out of stretched, damaged veins and depositing iron in the skin.
This is a C4 stage symptom and a strong red flag. Without treatment, this WILL progress to ulceration in 5-10 years. Act now — once developed, the discolouration may be permanent.
9. Hard, leather-like skin (lipodermatosclerosis)
The skin around the lower calf becomes hard, tight, and leather-like — feels like wearing a tight invisible boot. Often painful. This is C4b stage and the LAST warning before venous ulceration.
At this stage, modern treatment EVLT or RFA is the only way to stop further damage.
10. Open sore or ulcer that won't heal (venous ulcer)
An open wound, usually around the inner ankle, that has not healed in 4-6 weeks despite normal dressing and antibiotics. This is C6 — the most advanced stage.
Most venous ulcers heal within 12 weeks once the underlying refluxing vein is sealed by EVLT/RFA + compression therapy. Without intervention, ulcers can persist for 5-10+ years. See stage 6 varicose vein ulcer treatment.
11. Bleeding from a varicose vein
Spontaneous bleeding from a thin-walled varicose vein after minor trauma (or even none) — can be alarming and surprisingly heavy. Apply firm pressure for 10 minutes, elevate the leg above heart, and reach an ER. Always indicates urgent need for definitive treatment.
12. Hard, painful, rope-like vein (superficial thrombophlebitis)
A varicose vein that suddenly becomes hard, tender, warm, red, and rope-like — the vein has clotted (superficial thrombophlebitis). Not as dangerous as DVT but requires immediate doctor evaluation and Doppler ultrasound. Anti-inflammatories and definitive treatment within 4-8 weeks are usually needed.
When to see a vein specialist — symptom checklist
Book a Doppler ultrasound + vascular consultation if you have ANY 2 of these:
- Visible bulging veins for > 3 months
- Leg heaviness/aching by evening
- Ankle swelling at end of day
- Itching directly over veins
- Skin discolouration around ankles
- Night cramps not relieved by calcium/magnesium
The Doppler scan takes 25 minutes, costs ₹1,800, and gives you a definitive answer. Book online or call us directly.
Frequently Asked Questions
What are the very first symptoms of varicose veins?
The earliest symptoms are leg heaviness or tiredness by evening, mild ankle swelling after long standing, and small bluish veins becoming visible on the calves. These appear 2-5 years before classic bulging veins develop.
Are varicose veins always painful?
No. About 30% of patients have visible varicose veins without any pain — known as "asymptomatic varicose veins." But asymptomatic doesn't mean harmless — the underlying venous reflux can still progress to skin damage and ulcers.
Can varicose veins cause leg cramps at night?
Yes, very commonly. Up to 60% of varicose vein patients experience night-time calf cramps. This usually resolves within 2-4 weeks of endovenous closure of the diseased vein.
What does serious varicose vein pain feel like?
Severe varicose vein pain is dull, aching, and throbbing — often described as "tired heavy legs." It is worst in the evening, after standing/sitting, and improves with leg elevation. Sharp shooting pain or sudden severe pain may indicate clotting (thrombophlebitis or DVT) and needs urgent evaluation.
When are varicose veins symptoms an emergency?
Seek emergency care if you have: sudden swelling and warmth in one leg only, bleeding from a vein, sudden chest pain or breathlessness (possible pulmonary embolism), or hard tender red rope-like vein. Otherwise see a vascular specialist within 2-4 weeks.
Can varicose veins symptoms come and go?
Symptoms often fluctuate — worse during summer, in pregnancy, after long flights, with weight gain, or during menstruation. Hormonal changes and heat dilate veins further. The underlying disease, however, only progresses with time.
