Is Shoulder Embolization Painful? What to Expect

Quick Answer

Most patients find shoulder embolization only mildly uncomfortable: a numbing shot at the wrist and some pressure or aching in the shoulder. A sore shoulder for several days afterward is common and usually settles within about 2 weeks.

When your shoulder already hurts most of the day, the idea of a procedure that might add pain is hard to accept. The good news is that shoulder embolization is done through a small needle puncture, usually at the wrist, not through an incision in the shoulder. Most of what people feel is brief and manageable. Here is what published studies describe, step by step, and where discomfort is most likely.

The short answer on pain

For most patients, the procedure itself is not very painful. The main sensations are a numbing injection at the wrist, some pressure, and, in some cases, a temporary ache or warmth in the shoulder while the embolic agent is delivered. Afterward, a sore shoulder for several days is common and expected. In a 2025 Taiwanese study of 25 patients, 9 (36%) had this kind of short-term "post-embolization" pain, and it resolved within 2 weeks in every case.

Everyone experiences pain differently, and the agent your doctor uses can make a difference. A large 2025 study of 431 patients treated in several joints found that pain at the treated site lasting more than 7 days ranged from about 6% to 22% depending on the type of temporary embolic material used.

Before the procedure

Preparation is usually simple. You may be asked to avoid eating for a few hours beforehand, review your medications (especially blood thinners), and arrange a ride home. Your care team will typically check kidney function and ask about any allergy to contrast dye, since contrast is used to map the arteries. If you are not sure you are a good fit yet, start with our guide to who is a candidate for frozen shoulder embolization.

What happens during shoulder embolization

Numbing the access site. In published studies, the artery is usually reached through the wrist (radial artery) or, less often, just above the elbow or in the groin. The skin is numbed with local anesthetic. You will feel a pinch and a brief sting, similar to having blood drawn or an IV placed.
Placing a thin catheter. A small tube is guided from the wrist up to the arteries around the shoulder under live X-ray. Arteries do not have pain nerves on the inside, so most people do not feel the catheter moving.
Mapping the vessels. Contrast dye is injected to show which small arteries are feeding the inflamed area. Many people notice a brief warm feeling when contrast is injected.
Treating the abnormal vessels. The embolic agent is delivered into the targeted branches. Some patients feel a deep ache or pressure in the shoulder during this step, which typically fades.
Finishing up. The catheter is removed and a compression band is placed on the wrist. No stitches are needed.

In a 2024 Spanish study of 20 patients, the median procedure time was about 33 minutes. The 2025 Taiwanese study performed the procedure under local anesthesia, and the number of arteries treated averaged about 4 per patient.

Will I be awake?

In the studies we reviewed, shoulder embolization was done under local anesthesia, sometimes with light sedation to help you relax. General anesthesia is not usually needed. Being awake has an advantage: you can tell the team right away if you feel unusual pain, tingling, or skin discomfort. Ask your doctor exactly which type of sedation they use and whether you can eat beforehand.

Questions worth asking about comfort

Will I get anything to help me relax, and do I need someone to drive me home?
Which artery will you use, and how long will the wrist band stay on?
Which embolic agent do you use, and how often do your patients have a sore shoulder afterward?
What pain medicine should I take at home, and what should I avoid?
Who do I call after hours if something does not feel right?

Knowing the answers ahead of time tends to make the day itself much less stressful.

Right after the procedure

You will rest while the access site is watched. In the Taiwanese study, patients went home after a 4-hour observation period. The wrist compression band is usually loosened gradually. Practices differ, and the Spanish study kept patients in the hospital for a median of 1.6 days, so do not assume your plan will match any single study.

Common things you might notice in the first day or two:

Mild tenderness or a small bruise at the wrist
A dull ache in the shoulder
Faint pink or red patches of skin over the shoulder, which were seen in 24% of patients in the Taiwanese study and faded on their own

Our article on shoulder embolization risks and side effects explains these in more detail, including the rare serious ones.

Managing discomfort in the first two weeks

Most short-term pain after embolization is handled with simple measures. Your doctor may suggest:

Over-the-counter pain relievers, if they are safe for you
Ice packs on the shoulder in short sessions
Keeping the wrist clean and dry, and avoiding heavy lifting with that hand for a short period
Continuing gentle range-of-motion work when cleared, rather than holding the arm completely still

It can feel confusing to have more shoulder ache right after a pain-relief procedure. This is usually a short inflammatory response in the treated tissue. In the 2017 Japanese study of 25 patients, night pain improved by more than half within 1 week in 67% of patients, so for many people the overall direction is better, not worse, even early on. Our recovery timeline covers what usually happens week by week.

How it compares to other shoulder procedures

If you have had a steroid injection or hydrodilatation, embolization is usually less uncomfortable at the shoulder itself, because no needle goes into the joint. The trade-off is that embolization is a catheter procedure with its own small risks, such as bruising at the wrist and, rarely, problems with the artery. Surgical options such as manipulation under anesthesia and capsular release are done under general anesthesia and involve more recovery.

When to call your doctor

Call the office promptly if you notice:

Shoulder pain that is getting steadily worse after the first few days instead of better
A skin patch over the shoulder that darkens, blisters, or opens
Swelling, coldness, numbness, or color change in the hand on the side of the wrist puncture
Bleeding from the wrist that does not stop with firm pressure
Fever or redness spreading from the puncture site

Call 911 for chest pain, trouble breathing, sudden vision changes, confusion, or weakness on one side of the body.

Frequently Asked Questions

Does shoulder embolization hurt more than a cortisone shot?

Most people find the procedure itself comparable or less uncomfortable at the shoulder, since the needle goes into the wrist, not the joint. Afterward, a few days of shoulder ache is more common than after a simple injection.

How long does pain last after shoulder embolization?

Short-term post-procedure pain usually settles within days. In one 2025 study, all cases resolved within 2 weeks, but pain lasting more than a week happened in a minority of patients in a larger study.

Will I be put to sleep?

Published studies describe local anesthesia, sometimes with light sedation. General anesthesia is not usually required. Ask your doctor what they use.

Can I drive myself home?

If you receive any sedation, plan on someone else driving you home. Your doctor will tell you when it is safe to drive again.
