Is Tennis Elbow Embolization Painful? What to Expect

Quick Answer

Most people find elbow embolization tolerable: the main sensations are a numbing sting at the wrist, brief warmth from the dye, and sometimes a deep ache at the elbow. Soreness, bruising or a pain flare for several days afterward is common and usually temporary.

"Will it hurt?" is one of the first questions people ask about elbow embolization, and it is a fair one. You have already lived with a painful elbow for a long time. The honest answer is that the procedure itself is usually tolerable, while the elbow can be sore for a few days to a week or more afterward. Here is what that looks like, step by step.

How the procedure is done, in plain terms

Elbow embolization is performed from inside the blood vessels. There is no incision at the elbow and no stitches. In the published reports from Dr. Yuji Okuno's group in Japan, where the technique was developed, a catheter was placed through the radial artery at the wrist under local anesthesia, and the procedure took about an hour.

A very thin tube is guided from the wrist up to the small arteries around the elbow while the doctor watches on a live X-ray screen. Contrast dye shows where abnormal vessels are feeding the sore tendon. Tiny particles are then released to reduce blood flow into those vessels. For the bigger picture of why this is thought to help, see our tennis elbow embolization overview.

Before you arrive

Your visit typically starts days ahead. Expect the office to review your medications, kidney function if needed, allergies (especially to contrast dye or iodine), and any imaging. You may be asked not to eat for a few hours beforehand if sedation is planned. Arrange for someone to take you home, and wear a loose short-sleeved or easy-to-roll-up top.

Tell the team if you take blood thinners, have diabetes, or have had a reaction to contrast dye before. Do not stop any medication on your own.

What you will feel during the procedure

The numbing shot

The first thing most people notice is a brief sting and burn as local anesthetic is injected into the skin over the artery. After that, the puncture site should feel like pressure rather than sharp pain.

The catheter

Most people do not feel the catheter moving up the arm. Some describe a vague pressure, and others notice nothing at all.

The contrast dye

When dye is injected into arm arteries, many people feel a brief warm sensation in the forearm or hand. It passes in seconds.

The embolization itself

As particles are delivered near the painful tendon, some people feel a deep ache or a temporary flare of their usual elbow pain. Tell the team if it becomes uncomfortable; they can pause or give you more medication.

You will be awake or lightly sedated, depending on the plan. Whether sedation is offered, and what kind, is something to ask about at your consultation.

Right after the procedure

Once the catheter is out, a compression band is usually placed around the wrist to stop bleeding from the artery puncture. It is tightened at first and then loosened over a period of time. Your fingers may feel a little tingly or cool while the band is on; let the nurse know if it bothers you.

Because access is through the wrist rather than the groin in many elbow cases, people can usually sit up soon afterward. After a period of observation, most go home the same day.

The first few days: what is normal

This is where most of the discomfort happens. Studies report several common, short-lived reactions:

Elbow soreness or a pain flare. A large 2025 study of 431 patients treated for joint and tendon problems with temporary particles found that pain at the treated site lasting more than seven days occurred in 5.8% to 22.1% of patients depending on the particle type, and it was more common in the elbow than in other joints. In other words, a lingering ache is not unusual after elbow treatment.
Bruising and swelling. A 2026 case report described temporary diffuse bruising, swelling, increased pain and reduced function right after the procedure, all of which improved within days.
Skin color changes. In a 2018 Korean study, one patient treated with microspheres developed reddish skin over the forearm, which is thought to be related to particles reaching small skin branches.
Wrist tenderness at the puncture site.

A systematic review of shoulder and elbow embolization found that minor side effects in 27 of 143 patients (18.9%) went away on their own or with oral pain medication.

Managing discomfort at home

Use the pain relievers your doctor recommends.
Ice the elbow in short sessions if advised.
Rest from heavy gripping and lifting for the period you are told.
Keep the wrist puncture site clean and dry as instructed.

Questions to ask about comfort before you commit

Feeling prepared makes a real difference in how the day goes. Consider asking:

Will I have sedation, or only numbing medicine? Can I ask for more medicine during the procedure if I need it?
Which artery will you use, and how long will the wrist band stay on?
Which particle do you use? Studies suggest the chance of a lingering pain flare can differ by particle type.
What pain medicine should I have at home, and which ones should I avoid?
How soon can I type, drive, or go back to work?
Who do I call after hours if something does not feel right?

It also helps to plan your week. If your job involves heavy gripping, lifting or tools, consider scheduling the procedure before a lighter stretch of days. People who type or use a mouse all day may find the treated arm tires quickly at first. None of this means something is wrong; it is simply part of giving a sore tendon time to settle.

When to call the office or seek urgent care

Call promptly or go to an emergency department if you notice:

Bleeding from the wrist that does not stop with firm pressure, or a rapidly growing lump.
A hand that is cold, pale, numb or weak.
Skin over the forearm or elbow that turns dark, blistered or breaks down.
Fever, chills, or spreading redness and warmth.
Severe pain that is getting worse instead of better.
Hives, wheezing or swelling of the face after the procedure.

These are uncommon, but you should never wait them out. Our article on risks and side effects explains each one in more detail.

How it compares with other elbow treatments

People often compare embolization with a cortisone shot or PRP injection, which are quick but involve a needle directly into a tender area. Embolization takes longer and includes an artery puncture, but there is no needle into the tendon itself. Surgery, by comparison, involves an incision, a splint for about a week according to AAOS, and months of rehabilitation. Every option has some discomfort; the right choice depends on your situation. You can see how embolization fits alongside other procedures in our embolization guide.

Frequently Asked Questions

Will I be put to sleep for elbow embolization?

General anesthesia is not typically needed. Published reports describe local anesthesia at the wrist, and some practices add light sedation. Ask Dr. Fox which approach he uses.

How long does the procedure take?

In reports from the group that developed it, the procedure took about an hour. Plan for extra time for preparation and observation afterward.

Is it normal for my elbow to hurt more after embolization?

Yes, a temporary flare is common. In a 2025 study, pain lasting more than a week was more common after elbow treatment than other joints, but it generally settled.

Can I drive myself home?

If you receive any sedation, you should not drive that day. Even without sedation, having someone with you is wise because your wrist will be bandaged.
