Recovery after shoulder embolization does not happen all at once. Pain, especially night pain, tends to ease first. Range of motion usually follows more slowly over weeks to months, often with help from physical therapy. The timeline below is built from published studies, so it reflects averages. Your own recovery may be faster or slower, and a minority of patients do not improve as much as they hoped.
Recovery at a glance
| Time after procedure | What studies have reported |
|---|---|
| Same day | Observation, then home for many patients (4 hours in one 2025 study); some programs keep patients overnight |
| Days 1 to 14 | Temporary shoulder ache, wrist tenderness, and sometimes pink skin patches, which resolved within 2 weeks in one study |
| Week 1 | Night pain improved by more than half in 67% of patients in a 2017 study of 25 people |
| Month 1 | Night pain improved by more than half in 87% of that same group; motion starting to return |
| Month 3 | Most of the pain relief seen in studies has occurred; reaching and overhead motion continue to improve |
| Month 6 | Largest average improvements in pain, motion, and function in most studies |
Day of the procedure
After the catheter is removed from your wrist, a compression band stays on for a period while you rest. In a 2025 Taiwanese study of 25 patients, people were discharged after 4 hours of observation. A 2024 Spanish study had a median hospital stay of 1.6 days, which shows how much routines vary between programs. Plan to have someone take you home, take it easy for the rest of the day, and keep the wrist dressing clean and dry. You can read about the procedure itself in what to expect during shoulder embolization.
The first two weeks
This is the period when short-term side effects show up. In the Taiwanese study:
- 9 of 25 patients (36%) had a temporary ache in the shoulder after embolization
- 6 (24%) had pink or red skin patches over the shoulder
- 5 (20%) had a bruise or small collection of blood at the puncture site
All of these were mild and resolved within 2 weeks. During this stretch, most people go back to desk work and light daily activities within a few days, though you should follow your own doctor's guidance on lifting with the wrist that was used for access.
Many patients notice night pain easing surprisingly early. In the first Japanese pilot study in 2014, average night pain scores fell from 67 to 27 on a 100-point scale at 1 week. In a larger 2017 follow-up study, 16 of 24 patients (67%) had night pain cut by more than half within the first week.
Physical therapy and movement
Embolization is designed to calm pain and inflammation. It does not stretch a tight capsule by itself. That is why most programs pair it with exercise. In the Spanish study, patients went back to physical therapy 72 to 96 hours after the procedure and continued until their progress leveled off. Other studies let patients keep their existing therapy and medications. Less pain often makes stretching easier, which may help motion catch up. Our article on embolization and physical therapy explains how the two work together.

Weeks 3 to 6: the first month and beyond
By 1 month, studies report a clear trend in most patients:
- In the 2017 Japanese study, 21 of 24 patients (87%) had night pain cut by more than half within 1 month, and average worst-pain scores fell from 82 to 52 on a 100-point scale
- In a 2022 trial of 100 patients, average night pain dropped from 6.4 to 3.4 on a 10-point scale, and the ability to raise the arm forward improved from 97 to 119 degrees
- In the US investigational study of 20 patients, average pain fell by about 32 points on a 100-point scale at 1 month
Some patients improve less. In the Taiwanese study, 3 of 25 patients had a second embolization between about 4 and 9 weeks after the first because relief was not sufficient.
Months 2 to 3
For most people in published studies, pain keeps falling through the third month. In the 2017 study, average worst pain was down to 19 on the 100-point scale at 3 months. In the 2022 trial, average night pain was 2.3 out of 10, and forward arm elevation averaged 135 degrees. A 2026 meta-analysis that pooled 12 studies found outward rotation of the arm improved by about 26 degrees on average between 1 and 3 months after treatment. This is often the stage where reaching behind your back, fastening clothing, and sleeping on the affected side become easier.
Six months and beyond
Six months is the main checkpoint in most studies. Average results at that point included:
- Worst pain of 8 on a 100-point scale in the 2017 study, with shoulder function scores rising from 16 to about 84 out of 100
- Night pain of 1.6 out of 10 and forward elevation of 151 degrees in the 2022 trial
- Pain reduced by about 62 points on a 100-point scale in the US study, although only 12 of its 20 patients had 6-month data because the study ended early during the pandemic
Numbers on a scale are not the whole story. In the 2024 Spanish study of 20 patients, pain, motion, and function all improved significantly by 6 months, yet patient satisfaction scores barely changed. The authors did not fully explain why. It is a useful reminder to talk with your doctor about what a realistic good result looks like for you, such as sleeping through the night or reaching a high shelf, rather than expecting a shoulder that feels brand new.
In the 2017 study, motion and function kept improving during longer follow-up averaging about 3 years. How long results last is covered in how long shoulder embolization lasts.
What can slow recovery
- Diabetes. In the Spanish study, all 6 patients with diabetes still needed pain medication at longer-term follow-up.
- Mostly stiffness, not pain. If the capsule is very tight, motion may lag behind pain relief.
- Skipping exercises. Pain relief creates a window for stretching. Using it matters.
- A different source of pain. Neck problems, arthritis, or a large rotator cuff tear will not respond the same way.
Keep in mind that these figures come from studies without comparison groups, and frozen shoulder can also improve over time on its own. See the embolization guide and our shoulder embolization overview for more background.
When to call the office
Contact your doctor if shoulder pain is worsening after the first week, if a skin patch darkens or blisters, if your hand becomes cold, numb, or discolored, or if you develop fever. Call 911 for chest pain, sudden vision loss, or weakness on one side of the body.
Frequently Asked Questions
How soon will I feel better after shoulder embolization?
Many patients in published studies noticed less night pain within the first week, and most had meaningful relief within a month. Range of motion usually improves more gradually over 3 to 6 months.
When can I go back to work?
Desk work is often possible within a few days, but this depends on your job, whether sedation was used, and your doctor's instructions about the wrist used for access. Physically demanding work should be discussed individually.
Do I still need physical therapy after embolization?
Usually, yes. Embolization targets pain and inflammation, while exercises help restore motion. One study restarted therapy 72 to 96 hours after the procedure.
What if I don't improve?
Some patients improve less than others. In one study, 3 of 25 patients had a second embolization within about 2 months. Other options, such as injections or surgery, remain available.
