Varicose veins is very common and a very bothersome vascular problem. Although different studies give different incidences we can broadly say that it would affect 1 in 3 persons in their entire life time.
Veins are the pathway through which deoxygenated blood (impure blood) is pumped back to the heart. In your legs there are two types of veins, deep vein and superficial vein. Varicose veins occurs when the superficial veins get damaged. Basically it occurs when the one way valves ( similar to those present in a water pipes ) stop functioning. So blood flow which has to pumped back to the heart fails and starts pooling in the legs.
Because it affects our legs people often tend to ignore this very problematic and debilitating disease. People who are affected by varicose veins come with different complaints.
They might develop those visible ugly spider / snake type of veins. They might come with pain, swelling, itching, difficulty in walking, leg tiredness, blackish / reddish discolouration of skin, bleeding or sometimes none of it. Often ignored it eventually leads to dreaded complications like Ulceration, Cellulitis and rarely even maggots infection of those ulcers.
