Understanding Shoulder Pain and Shoulder Injuries

5/8/2026

Shoulder pain is one of the leading reasons people seek orthopedic care. Because the shoulder is the most mobile joint in the human body, it is also one of the most vulnerable to injury, wear and degeneration over time. When something goes wrong, even small movements like reaching overhead, lifting a bag of groceries or getting dressed can become painful.

At Lakeside Physicians, orthopedic surgeons Cody Hartshorn, M.D., and Corey Mark, M.D., diagnose and treat a wide range of shoulder problems, from simple strains to advanced arthritis that may require joint replacement.

Common Causes of Shoulder Pain

1. Rotator Cuff Tears
   The rotator cuff is a group of muscles and tendons that stabilize the shoulder. Tears can occur gradually from wear and tear or suddenly from a fall or heavy lifting.
2. Shoulder Impingement
   When the tendons of the rotator cuff get pinched under the shoulder blade, inflammation and pain develop.
3. Arthritis of the Shoulder
   As cartilage wears down, the ball and socket joint becomes painful and stiff.
4. Tendonitis or Bursitis
   Inflammation of the tendons or bursae around the shoulder can cause sharp pain with reaching or lifting.
5. Labral Tears
   The labrum is a ring of cartilage that stabilizes the shoulder socket. Tears may occur from sports, heavy lifting, or aging.
6. Dislocations and Instability
   Younger athletes or those with loose ligaments may experience repeated dislocations.

When to See an Orthopedic Surgeon

Seek an evaluation for:

• Persistent shoulder pain
• Loss of strength
• Nighttime pain interfering with sleep
• Grinding or popping sensations
• Shoulder instability
• Stiffness limiting daily activity

How Shoulder Pain Is Treated

Nonsurgical Approaches:

• Physical therapy
• Anti-inflammatory medications
• Activity modification
• Ice, stretching, and posture correction
• Corticosteroid injections

When Surgery Is Needed:

• Arthroscopic surgery for rotator cuff repair, bone spur removal, or labral tears
• Shoulder stabilization for recurrent dislocations
• Shoulder replacement for severe arthritis or massive rotator cuff damage

Doctors Cody Hartshorn, M.D., and Corey Mark, M.D., help restore comfort, strength and mobility for patients with shoulder arthritis, rotator cuff injuries, impingement, bursitis, instability and more.
