What is the condition when blood vessels in the arm are swollen?

Swollen blood vessels in the arm can be caused by several different conditions. Here are some common causes:

1. Phlebitis (Vein Inflammation)

• Description: Phlebitis is the inflammation of the veins, which causes the blood vessels to swell and become painful. Phlebitis can occur due to infection or injury (such as from injections into the veins).

• Symptoms: Swollen, red veins, pain, and a warm feeling in the affected area.

2. Deep Vein Thrombosis (DVT)

• Description: This condition occurs when a blood clot (thrombosis) forms in the deep veins, often in the legs, but it can also happen in the arms. The clot can cause swelling in the blood vessels and pain.

• Symptoms: Swelling, pain, and redness in the affected area. This is a serious condition and can lead to dangerous complications if not treated promptly.

3. Carpal Tunnel Syndrome

• Description: This condition occurs when the nerves and blood vessels in the wrist are compressed, leading to swelling and pain. While this is primarily a nerve-related issue, the compression can also affect the blood vessels and cause swelling.

• Symptoms: Tingling, numbness, pain in the wrist and fingers, and possibly mild swelling.

4. Varicose Veins

• Description: This occurs when veins become enlarged, twisted, and bulging, commonly found in the legs, but varicose veins can also occur in the arms.

• Symptoms: Swollen veins, pain, and visible twisted veins under the skin.

5. Injury or Trauma

• Description: Swelling of blood vessels can occur due to injuries or blows to the arm, which damages the blood vessels and causes swelling.

• Symptoms: Swelling, bruising, and pain in the injured area.

6. Cellulitis

• Description: Cellulitis is a soft tissue infection caused by bacteria that can affect the blood vessels in the arm, leading to swelling and redness.

• Symptoms: Swelling, redness, warmth, and pain in the infected area.

When to See a Doctor?

• Severe pain, especially when touched.

• Swelling that lasts or worsens over time.
