What causes pain associated with varicose veins?

From the Guidelines

Varicose vein pain is primarily caused by blood pooling in weakened veins, leading to pressure and inflammation, as a result of incompetent valves, weakened vascular walls, and increased intravenous pressure. The exact pathophysiology is debated, but it involves a genetic predisposition, and risk factors include family history of venous disease; female sex; older age; chronically increased intra-abdominal pressure due to obesity, pregnancy, chronic constipation, or a tumor; and prolonged standing 1. Symptoms of varicose veins include a heavy, achy feeling and an itching or burning sensation; these symptoms worsen with prolonged standing 1.

Some key points to consider when evaluating varicose vein pain include:

• Localized symptoms may be unilateral or bilateral and include pain, burning, itching, and tingling at the site of the varicose veins 1
• Generalized symptoms consist of aching, heaviness, cramping, throbbing, restlessness, and swelling in the legs 1
• Symptoms are often worse at the end of the day, especially after prolonged standing, and usually resolve when patients sit and elevate their legs 1
• Women are significantly more likely than men to report lower limb symptoms 1

To manage varicose vein pain, consider the following measures:

• Elevate your legs above heart level for 15-30 minutes several times daily
• Wear compression stockings (20-30 mmHg pressure) during waking hours
• Take over-the-counter pain relievers like ibuprofen (400-600mg every 6-8 hours) or acetaminophen (500-1000mg every 6 hours) as needed
• Regular low-impact exercise such as walking or swimming for 30 minutes daily improves circulation and reduces discomfort
• Avoid prolonged standing or sitting, and take breaks to move around every hour
• Apply cool compresses to painful areas for 15-20 minutes to reduce swelling
• For immediate relief at night, elevate the foot of your bed 4-6 inches using books or blocks, as suggested by 1.

It's essential to note that while these measures can help alleviate symptoms, if pain persists or worsens despite these measures, consult a healthcare provider as medical procedures like sclerotherapy or endovenous laser treatment may be necessary 1.

From the Research

Causes of Pain Associated with Varicose Veins

The pain associated with varicose veins is caused by several factors, including:

• Damages to blood vessels leading to painful swelling and blood clots 2
• Prolonged standing and obesity, which are major reasons for varicose vein disease 2
• Pathological venous reflux, arising from a weakness of the vein wall and progressive venous insufficiency 3
• Chronic venous disease, which is manifested by a spectrum of signs and symptoms, including large painful varicose veins, edema, and hyperpigmentation of skin 4

Symptoms of Varicose Veins

The symptoms of varicose veins include:

• Pain, swelling, and heaviness of the legs 3
• Cosmetic spider veins, asymptomatic varicosities, and large painful varicose veins 4
• Edema, hyperpigmentation, and lipodermatosclerosis of skin, and ulceration 4

Treatment Options for Varicose Veins

The treatment options for varicose veins range from conservative to minimally invasive and invasive, including:

• Compression therapy and venoactive drugs for conservative therapy 3
• Endovenous thermal ablation, sclerotherapy, and surgical techniques for minimally invasive and invasive therapy 5, 3
• Compression therapy after invasive treatment to eliminate varicose veins and reduce postoperative pain 6
