Can’t Lift Your Arm Overhead? Here’s What Could Be Wrong

ByKevin Kruse

Difficulty lifting your arm overhead can be caused by a massive rotator cuff tear, frozen shoulder, shoulder impingement, calcific tendonitis, shoulder arthritis, or nerve injury. Dr. Kevin Kruse and our experienced clinical team specialize in evaluating shoulder pain, identifying the underlying cause, and creating individualized treatment plans to restore comfort, mobility, and function.

This page explains why you may not be able to lift your arm overhead, common causes to consider, treatment options, and when to schedule an evaluation with a shoulder specialist.

Key Takeaways

  • Difficulty lifting the arm overhead may be caused by a massive rotator cuff tear, frozen shoulder, shoulder impingement, calcific tendonitis, shoulder arthritis, or nerve injury.
  • There is a difference between painful lifting and true inability to lift the arm. Painful lifting often occurs with impingement, calcific tendonitis, or arthritis, while sudden weakness or loss of function may point to a massive rotator cuff tear or nerve injury.
  • Sudden loss of lifting ability, night pain, a “dead arm” feeling, major weakness, burning pain, numbness, or tingling should be evaluated promptly by a shoulder specialist.

Understanding Shoulder Pain When Lifting The Arm

There are two general patterns of shoulder pain when lifting the arm: Pain you can work through while still raising the arm, and pain, weakness, stiffness, or dysfunction that prevents you from lifting the arm at all.

Discomfort you can work through may suggest irritation or inflammation around the tendons, bursa, or shoulder joint. Pain or dysfunction that stops the arm from lifting may point to a more significant problem, such as rotator cuff damage, frozen shoulder, advanced arthritis, or nerve involvement affecting shoulder strength.

Common Causes Of Shoulder Pain When Lifting Your Arm

Shoulder pain when lifting the arm can have a variety of underlying causes, including:

Complete Rotator Cuff Tear

A rotator cuff tear occurs when one or more of the rotator cuff tendons, which help lift and stabilize the shoulder, become completely torn away from the upper arm bone (humerus) and can no longer function normally. Without proper tendon support, the shoulder may no longer have the strength or control needed to raise the arm overhead.

Patients may notice a sudden inability to lift the arm after a fall, lifting injury, or forceful movement. Weakness, night pain, or a “dead arm” feeling can also suggest a more serious tear that should be evaluated quickly for the best long-term outcomes.

Frozen Shoulder

Frozen shoulder, also called adhesive capsulitis, causes pain and progressive stiffness that makes the shoulder difficult to move. Adhesions, or sticking points, can form in the shoulder capsule and limit reaching overhead, away from the body, or behind the back.

Shoulder Impingement

Shoulder impingement occurs when the rotator cuff tendons become pinched in the small space beneath the acromion, the bony upper arch of the shoulder, during movement. Patients may feel a sharp pinching sensation when lifting the arm overhead, which can cause them to avoid raising the arm fully.

Calcific Tendonitis

Calcific tendonitis occurs when calcium deposits build up in the rotator cuff tendons after long periods of tendonitis or overuse, leading to inflammation and sometimes mechanical irritation. If the deposits cause impingement beneath the acromion, overhead motion may become painful or limited.

Shoulder Arthritis

Shoulder arthritis occurs when cartilage loss and inflammation interfere with smooth movement between the ball and socket of the glenohumeral joint. Patients may notice deep joint pain, stiffness, grinding, clicking, loss of motion, or difficulty reaching overhead or behind the back.

Nerve Injury

A nerve injury can cause burning pain, weakness, numbness, tingling, or difficulty activating certain shoulder muscles. Cervical nerve root impingement (a pinched nerve in the neck) can also lead to pain or weakness with overhead lifting, especially if nerve compression has caused muscle atrophy over time.

How Shoulder Pain Is Treated

Treatment for shoulder pain when lifting the arm depends on the diagnosis, severity of symptoms, patient goals, and whether the issue is inflammatory, structural, arthritic, or nerve-related.

Non-surgical care may include activity modification, short-term anti-inflammatory medication, physical therapy, injections, and a guided return to activity. If symptoms are related to nerve involvement from the neck, consultation with a spine specialist may be recommended.

When symptoms are caused by a significant structural problem, such as a large rotator cuff tear, advanced arthritis, or persistent mechanical impingement, a procedure may be considered if non-surgical treatment isn’t enough to restore comfort and function.

What To Do If You Can’t Lift Your Arm

What to do about shoulder pain when lifting the arm depends on the type and severity of symptoms you’re experiencing:

  • For mild pain that comes on gradually, short-term rest from painful movements, ice, activity modification, and avoiding repetitive overhead use may help. If symptoms improve over a few days and shoulder function returns to normal, the issue may have been temporary irritation.
  • For more severe pain following an injury, sudden inability to lift the arm, major weakness, night pain, a “dead arm” feeling, visible muscle atrophy, or symptoms that continue to worsen despite rest and at-home care, it’s important to schedule an evaluation with a shoulder specialist. Many shoulder injuries are more treatable when diagnosed early, so prompt assessment is strongly recommended.

Understanding The Cause Of Your Shoulder Pain

When you can’t lift your arm normally, the goal of an evaluation is to identify the underlying cause of your symptoms and tailor a treatment plan to your needs. Dr. Kruse and our clinical team use a combination of physical examination and diagnostic imaging to evaluate range of motion, strength, painful arc, stiffness, rotator cuff function, neck involvement, nerve symptoms, and joint mechanics.

Once a diagnosis has been confirmed, our team can help you understand your treatment options and recommend the most appropriate next step.
