Quick answer
What is Varicose veins?
Varicose veins are enlarged, twisted veins that appear blue or dark and bulge under the skin, most often in the legs. They develop when the one-way valves inside the veins weaken, allowing blood to flow backwards and pool.
- How it is treated: Many varicose veins need no treatment beyond reassurance and simple measures.
- Self-care: Staying active, avoiding long periods of standing or sitting still, elevating the legs when resting, maintaining a healthy weight, and wearing compression stockings if advised can ease symptoms.
- When to seek help: See a GP if varicose veins ache, cause skin changes or swelling, bleed, or if the skin near the ankle becomes discoloured or breaks down (a possible ulcer).
What it is
Varicose veins are enlarged, twisted veins that appear blue or dark and bulge under the skin, most often in the legs. They develop when the one-way valves inside the veins weaken, allowing blood to flow backwards and pool. This is very common and often causes no more than a cosmetic concern, but some people have aching, heaviness, itching, swelling or cramps, especially after standing. Occasionally complications develop, such as skin changes, inflammation (phlebitis) or, rarely, ulcers. Risk factors include family history, older age, pregnancy, being overweight and jobs involving long periods standing.
How it is treated
Many varicose veins need no treatment beyond reassurance and simple measures. When they cause troublesome symptoms or complications, several effective procedures can close or remove the affected veins, such as heat (laser or radiofrequency) treatment, injection therapy, or surgery. The choice depends on the veins involved and individual factors, and is discussed with a specialist. Compression stockings may ease symptoms, particularly if a procedure is not suitable or wanted.

Beyond medication
Lifestyle and self-care
Staying active, avoiding long periods of standing or sitting still, elevating the legs when resting, maintaining a healthy weight, and wearing compression stockings if advised can ease symptoms.
When to get help
When to see a doctor
See a GP if varicose veins ache, cause skin changes or swelling, bleed, or if the skin near the ankle becomes discoloured or breaks down (a possible ulcer). Sudden painful swelling of a leg needs urgent assessment to rule out a clot.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
