A tingling sensation in the legs—whether occasional or persistent—is a symptom many people experience but often ignore. It may feel like pins and needles, numbness, or even a mild burning or crawling sensation. While temporary tingling can result from sitting too long or crossing your legs, chronic or unexplained tingling may indicate an underlying medical or vascular condition that requires professional attention.

At Apex Heart & Vascular Center in Cypress, TX, we help patients get to the root of their leg symptoms. Understanding what causes tingling in the legs is the first step toward relief—and protecting your long-term vascular health.

What Causes Tingling in the Legs?

Tingling, also called paresthesia, can stem from a variety of issues affecting the nerves, blood vessels, or musculoskeletal system. Some of the most common causes include:

• Nerve Compression – Sitting for extended periods, poor posture, or spinal issues can press on nerves and cause tingling.

• Peripheral Neuropathy – Nerve damage due to diabetes, alcohol use, or vitamin deficiencies (especially B12) can lead to numbness, pain, and tingling.

• Restless Leg Syndrome (RLS) – A neurological condition that often causes tingling or crawling sensations, especially at night.

• Sciatica – Compression of the sciatic nerve can cause radiating tingling from the lower back down to the leg.

While these causes are common, vascular conditions are often overlooked—but just as important to consider.

When Tingling in the Legs Is Vascular-Related

Your circulatory system plays a vital role in nourishing the nerves and tissues in your legs. When blood flow is impaired, nerves may not receive enough oxygen or nutrients, leading to abnormal sensations such as tingling or numbness.

Three common vascular issues we see at Apex that may cause tingling in the legs include:

1. Peripheral Artery Disease (PAD)

PAD causes arteries in the legs to narrow or become blocked, reducing blood flow. Tingling, pain while walking, or leg fatigue can be early signs.

2. Chronic Venous Insufficiency

Weakened vein valves can lead to blood pooling in the legs, causing pressure, swelling, and tingling—often worsening at the end of the day.

3. Deep Vein Thrombosis (DVT)

A blood clot in a deep vein can interfere with circulation and cause pain, swelling, or tingling in one leg. This is a serious condition that needs urgent care.

How We Diagnose and Treat Leg Tingling at Apex

At Apex Heart & Vascular Center, our Cypress team uses state-of-the-art diagnostics to evaluate the cause of your symptoms. This may include:

• Vascular ultrasound

• Ankle-brachial index (ABI)

• Echocardiograms or EKGs (if heart-related concerns exist)

• Lab work to check for vitamin deficiencies or diabetes

Once we identify the root cause, we create a treatment plan tailored to you. This could include:

• Lifestyle changes to improve circulation

• Medication to manage blood pressure, cholesterol, or nerve function

• Minimally invasive procedures like angioplasty or vein ablation

• Nutritional support or physical therapy, depending on your diagnosis

When to See a Vascular Specialist

You should schedule a consultation with a vascular specialist if:

• Tingling persists or worsens over time

• It affects only one leg or is accompanied by swelling

• You have risk factors like diabetes, smoking, or family history of vascular disease

• You notice color changes in the skin or visible varicose veins

• You’ve experienced unexplained leg pain, especially while walking
