Symptoms
How it tends to show up
A pinch or catch when lifting the arm to shoulder height or above; pain reaching behind your back or into a sleeve; an ache on the outside of the shoulder that can run down the arm; pain that disturbs sleep, especially lying on that side; weakness or reluctance to lift overhead.
How Common
You're not alone in this
Shoulder impingement is the single most common reason people see someone for shoulder pain — by some estimates it accounts for roughly 44 to 65% of all shoulder complaints. It tends to peak in our 50s and shows up most in people who reach overhead a lot, whether that's swimmers and volleyball players or painters, carpenters, and hairdressers. Why does that matter to you? Because this isn't a rare or mysterious problem — it's a very well-understood, very treatable condition, and the large majority of people get better without ever needing surgery.
The Root
Why it keeps coming back
Impingement is usually a movement problem, not just a structural one. When the rotator cuff and the muscles that position the shoulder blade aren't firing in the right sequence, the head of the arm bone drifts upward as you lift, and the tendons get pinched against the bone above them. Rest and anti-inflammatories calm the irritation, but if the shoulder still moves the same way, the pinching — and the pain — comes back.
Who Gets It
Common risk factors
- Repetitive overhead reaching, lifting, or throwing
- Overhead sports — swimming, volleyball, baseball, tennis
- Manual trades — painting, construction, drywall, hairstyling
- Age (incidence tends to peak around the 50s)
- Rotator cuff weakness or fatigue
- Scapular dyskinesis (the shoulder blade not moving well)
- Forward-head, rounded-shoulder posture
- Smoking and poor sleep, which can slow tendon healing
Look-Alikes
Is it Shoulder Impingement, or something else?
Several other problems can mimic this, and they're managed differently — so part of the assessment is telling them apart.
Wondering if this is what's going on — and what care would look like?
Book an Assessment →The Approach
How Dr. Imada approaches it
Using Advanced Muscle Integration Technique (AMIT), I assess which rotator-cuff and shoulder-blade muscles have switched off and restore them, so the shoulder tracks properly and stops pinching during overhead motion. Chiropractic care addresses the neck and upper-back contributions, and we add movement work to retrain the pattern. This reflects what I consistently see help — shared as clinical insight, not a guarantee.
Getting Answers
How it's assessed
Shoulder impingement is diagnosed clinically far more than by scan — the physical exam carries a lot of the weight here. In the room I'll watch how your arm moves, looking for the classic painful arc roughly between 70 and 120 degrees of lifting, and use gentle tests like Neer and Hawkins-Kennedy that reproduce the pinch. What I'm really asking is why the subacromial space — the small gap your rotator cuff tendons glide through — has gotten crowded. Often it's not the tendon itself misbehaving but the muscles around the shoulder blade that have switched off, letting the joint drift and pinch with every reach. That whole-chain view is, in what I consistently see, the difference between quieting the pain for a week and actually changing the pattern. X-ray, ultrasound, or MRI come in only when things don't respond as expected or I suspect a true tear — and that's a moment I'd co-manage with a physician.
Your Visit
What to expect
An assessment of how the whole shoulder, shoulder blade, and neck work together; a clear read on why the tendon is being pinched; hands-on care to restore the muscles that control the joint; and a simple movement plan to keep the shoulder tracking well.
At Home
What you can do yourself
- Pull back temporarily from overhead and behind-the-back motions
- Keep your work inside a comfortable 'window' in front of you
- Ice the front and side of the shoulder after aggravating activity
- A short course of over-the-counter anti-inflammatories if appropriate for you
- Sleep off the painful side, with a pillow supporting the arm
- Gentle posture resets through the day to open the joint space
These steps calm the symptoms and protect the tendon, but they tend to work best alongside restoring the muscle control and movement pattern that let the pinch happen in the first place.
Outlook
Recovery & realistic timelines
Here's the honest timeline: most people start feeling better within a few weeks of starting the right care, but full recovery of a cranky tendon usually takes several months, and a stubborn case can run up toward a year. The encouraging part is that the majority of people reach a satisfactory outcome with conservative care — and notably, large trials have found surgery offers no reliable advantage over a good structured exercise program for ordinary impingement. My aim is to help shorten that arc by addressing why the cuff is overloaded — the switched-off muscles and the way load travels up the chain — rather than just waiting it out.
Staying Ahead
Keeping it from coming back
- Build and keep rotator cuff and shoulder-blade strength
- Increase overhead training load gradually, never in spikes
- Work within a comfortable window in front of your body
- Tend to posture — ease forward-head and rounded shoulders
- Quit smoking and protect your sleep for tendon health
- Keep up your home exercises once the pain settles

FAQ
Common questions
Will it heal on its own?
It often improves with rest and activity changes, but left fully unaddressed it can worsen over time and may progress toward a rotator cuff tear — which is exactly why addressing the underlying load pattern matters.
Do I need an MRI?
Usually not at first. Impingement is largely a clinical diagnosis, and I reserve MRI for cases that don't respond as expected or when I suspect a true tear — and I'd order that in coordination with a physician.
Will I need surgery?
Most people don't. Multiple high-quality studies show surgery offers no reliable benefit over structured exercise for typical impingement, so we start conservatively. If a true structural tear is found, that's a conversation to have with a surgeon.
Why does it hurt so much more at night?
Lying on the shoulder compresses the already-crowded space, and without daytime distraction the ache is simply more noticeable — it's a classic, expected feature.
Can I keep working out?
Usually yes, with modification — we pull back the overhead and pressing movements that pinch and keep loading the rest of you while the shoulder calms.
What about a cortisone shot?
Injections can give short-term relief that makes rehab easier, but repeated shots carry a real risk to the tendon, so they're best viewed as a bridge rather than a fix — and that's a decision coordinated with your physician.
Why are you looking at my shoulder blade and neck?
Because the pinch usually isn't a purely local problem — when the shoulder blade or deeper stabilizers switch off, the joint can drift and crowd the tendons. The goal is to address the cause, not just the sore spot.
Will it come back?
It can, if the overload pattern isn't addressed — which is why we rebuild the strength and movement control and keep you doing your home program.
How soon can I get back to my sport?
Many people feel better in weeks, but returning too early is a common cause of reinjury — we stage your return as strength and pain-free motion come back.
