An ulnar vein is found in the arm near the elbow. It’s a small vein that runs below the elbow down into the bicep.
It’s most commonly seen on the upper arm. It’s not a major vein, but it can get swollen with the arm in an extended position.
Ulnar bicep vein
When you have ulnar nerve damage, you might have a blocked ulnar vein. This condition is called ulnar nerve entrapment. Ulnar nerve damage is also called cubital tunnel syndrome.
Your ulnar nerve runs throughout the arm in a tunnel. Injuries to the nerve can cause compression of the vein.
Ulnar vein on the outside of the arm
Your ulnar vein is most commonly found on the outside of the upper arm. It can be found on the upper arm on the side of the arm that has the ulnar nerve. It’s also often found on the wrist on the side of the hand that has the ulnar nerve.
Ulnar vein on the inside of the elbow
Your ulnar vein is most commonly found on the inside of the elbow. It can be found on the inside of the elbow on the side of the arm that has the ulnar nerve.
How to identify a vein?
If you’re having a vein work-up, your primary care doctor will examine the area and ask you about your symptoms. They’ll ask you a few questions to help them find the vein and determine if it’s causing your symptoms.
They may ask you:
- If you’ve had a recent injury
- If you have high or low blood pressure
- If you have swelling
- If you have an infection
Once they’ve found the vein, your doctor will be able to determine exactly what’s causing the symptoms. They can also determine if your vein is blocking blood flow to your arm.
If your doctor determines that your vein is causing your symptoms, they may recommend blood thinners to help reduce the risk of blood clots.
How to check for a vein?
Your doctor will use a hand-held device called a Doppler to check for veins. This handheld device emits a low-frequency sound that bounces off the moving blood. It can detect the Doppler frequency.
When a vein is working normally, the Doppler frequency will be around 20 hertz. If your vein is blocked, the frequency will be between 130 and 140 hertz.
When veins are blocked, you can usually feel a pulsing sound or see a change in color.
The Doppler is painless and quick to use. You’ll need to be standing still to use it. A healthcare professional will give you the device and instruct you how to use it.
They may ask you to hold the device against the skin for a few seconds before moving it to the other arm. You can also use the device while sitting down.
How to find a vein?
It’s possible to find a vein on the skin. But locating a vein by touch is more difficult than finding a vein with a Doppler.
You can do this by looking for the vein’s color. Veins are red or purple in color. If you can see the vein, you should be able to feel it’s presence.
You might also be able to feel the vein if you press on it.
You can also use a handheld Doppler device. It emits a low-frequency sound that bounces off the moving blood. It can detect the Doppler frequency.
The Doppler can also be used to locate veins in the legs, feet, and hands.
What blood tests can detect a vein?
A blood test is a common way to find out if you have a blocked vein. This is because a blood test will detect any changes in your blood.
Depending on your symptoms, blood tests can help your doctor identify if you have a vein problem.
If you have a high blood pressure, your doctor may recommend a blood test to test for high blood pressure. A vein ultrasound can be used to find blocked veins.
However, if your doctor suspects that you have a blocked vein, they may recommend a blood test.
A blood test is not a diagnostic test. Instead, it helps your doctor identify if your veins are blocked.
What are the risks of blood tests?
Blood tests are a common way to find out if you have a blocked vein. However, there are risks involved with blood tests.
For example, you may need to stop a test if you have a lightheaded feeling. If you have a lightheaded feeling, you might feel dizzy or lightheaded. This might prevent you from holding the device on your arm well.
Your doctor might also ask you to stop the test if you’re experiencing pain or discomfort.

If you smoke, your doctor may also advise you to quit.
If you’re experiencing symptoms, your doctor will likely recommend a blood test to identify the cause of your symptoms.
What is the outlook for a blocked vein?
