Shoulder Pain From Lifting: Rotator Cuff and Biceps Tendon Problems, and What Actually Helps
By Dr. Bret Heiser, DC | Competitive Chiropractic and Rehab | Last updated: November 2026
Short answer: Most lifting-related shoulder pain comes from irritated tendons, usually the rotator cuff or the biceps tendon, not from a "torn" or "broken" shoulder. Most cases improve with the right mix of load management, targeted hands-on treatment, and progressive strengthening. If your shoulder has been bothering you for more than a few weeks, getting it assessed early shortens the road back.
Why shoulder pain is so common in CrossFit and lifting
The shoulder is the most mobile joint in your body, which means it relies heavily on small stabilizing muscles and tendons. Overhead pressing, kipping pull-ups, snatches, ring work, and high-volume bench pressing all load those tendons repeatedly. When training volume goes up faster than the tissue can adapt, the tendons get irritated. That is tendinopathy, and it is the most common reason athletes come to see me about their shoulders.
I have competed in multiple sports my whole life and I treat athletes inside a CrossFit gym every week, so I see this pattern constantly: a shoulder that "just started hurting" usually has weeks of buildup behind it.
Rotator cuff pain vs. biceps tendon pain
They often overlap, but there are some common differences.
Rotator cuff irritation tends to show up as a deep ache on the outer shoulder or upper arm. It is often worse when you raise your arm out to the side or overhead, and it commonly bothers you when lying on that shoulder at night.
Biceps tendon irritation (bicipital tendonitis) is typically felt at the front of the shoulder. Pressing, pulling, and catching a bar in the rack position can be the painful movements.
A proper exam is the only reliable way to tell them apart, and the difference matters because the rehab emphasis changes.
What actually helps
1. Adjust the load, don't just stop. Complete rest tends to leave the tendon weaker. Usually the better move is to reduce or swap the aggravating movements for a few weeks while keeping other training going. For example, you might replace kipping with strict work, or use a neutral-grip variation for pressing.
2. Hands-on treatment to calm the area down. Soft tissue work, joint mobilization, and dry needling can reduce pain and muscle guarding so you can move and load the shoulder better. Dry needling is one of my certified specialties and works well for the tight upper trap, rotator cuff, and surrounding muscles that tend to flare up alongside a sore tendon.
3. Progressive strengthening. This is the part that decides whether the problem stays fixed. Tendons respond to gradual, consistent loading, such as rotator cuff external rotation work, scapular control, and controlled overhead strength. Rehab built around your actual sport or training goals beats generic band exercises.
4. Shockwave therapy for stubborn cases. For tendon problems that have lingered for months or have stalled despite good rehab, shockwave therapy is another option. It uses acoustic pressure waves to stimulate the tissue. The research is strongest for calcific rotator cuff tendinopathy, and results are more mixed for other shoulder tendon problems, so I use it as part of a plan, not as a stand-alone fix. In my office, sessions are about 15 minutes, a typical course is 5 to 10 visits depending on how severe and how long-standing the problem is, and it is $100 per session with 50% off your first session.

When to get it checked sooner
Book an evaluation if you notice any of the following:
Pain that has lasted more than 2 to 3 weeks without improving
Night pain that keeps waking you up
Noticeable weakness, or trouble lifting your arm
Pain after a specific injury or a pop during a lift
Numbness or tingling down the arm
If you have shoulder or arm pain together with chest pressure, shortness of breath, or lightheadedness, treat it as an emergency and call 911.
What to expect at your first visit
We start with a history of your training and symptoms, then test your range of motion, strength, and the specific movements that bring on the pain. From there I explain what I think is going on, what you can keep doing, and what to change. Sessions are 15 to 30 minutes, and you will not be pushed into a long prepaid treatment plan. My focus is on getting you better and giving you the tools to keep training.
Frequently asked questions
Do I have to stop working out with shoulder tendonitis? Usually not completely. Most people do better modifying the painful movements and keeping the rest of their training going. An evaluation can tell you what is safe for your shoulder.
How long does rotator cuff or biceps tendon pain take to heal? Mild cases that are caught early can settle in a few weeks. Long-standing tendon problems commonly take several months of consistent rehab. Starting early makes a difference.
Is dry needling the same as acupuncture? No. Dry needling is based on modern anatomy and targets muscle and trigger points to reduce pain and restore movement. It is a technique I have been certified in since 2018.
Does shockwave therapy hurt? It is uncomfortable but tolerable for most people, and we adjust the intensity to you. Sessions are short, and there is no downtime afterward.
Do you take insurance for shockwave? Shockwave therapy is cash-pay only, so there is no insurance billing.
