Whether you need to grab a book from a tall shelf, bring in a heavy bag of groceries, or just brush your hair, shoulder pain can stop you in your tracks. While minor shoulder discomfort might fade on its own, ongoing pain can affect your ability to work, exercise, or enjoy daily life. That’s when you might start thinking about shoulder pain treatment from the team at [site-name].

To help you know when to visit us for shoulder pain, we’ve prepared this handy guide exploring the common causes of shoulder discomfort. We’ve also included some information about how physical therapy can help you recover safely and effectively.

Revealing The Common Causes of Shoulder Pain

The shoulder is a complex joint made up of bones, muscles, tendons, and ligaments that work together to support movement. Pain, stiffness, and weakness can follow when any part of this system is injured. Identifying the cause helps ensure you get the right shoulder pain treatment before it worsens. Here are some of the most common:

Rotator Cuff Injuries

The rotator cuff is a group of muscles and tendons that help lift and rotate your arm. It’s also one of the most commonly injured parts of the shoulder.

How Rotator Cuff Injuries Happen

  • Repetitive overhead motion (such as throwing a baseball or painting a house)
  • Sudden falls or trauma
  • Age-related wear and tear

Symptoms

  • Dull ache or sharp pain, especially when lifting your arm
  • Weakness in the shoulder
  • Difficulty sleeping on the affected side

When to Seek Help

If pain lasts longer than a few days or worsens with movement, physical therapy can help restore strength and prevent further injury.

Frozen Shoulder

Frozen shoulder (known medically as adhesive capsulitis) causes tissue in the shoulder joint to become stiff and painful over time. Researchers aren’t totally sure why frozen shoulder happens, but there are certain risk factors to be aware of.

Risk Factors for Frozen Shoulder

  • Being a woman between 40 and 60
  • Inactivity after injury or surgery
  • Conditions like diabetes or thyroid issues

Symptoms

  • Intense pain
  • Gradual loss of shoulder movement
  • Trouble with simple tasks like dressing or reaching overhead

When to Seek Help

Early shoulder pain treatment is important to restore movement before the joint becomes more restricted, so contact our team at [site-name] as soon as you notice symptoms.

Shoulder Impingement

Shoulder impingement occurs when the space between the shoulder bones narrows, causing tendons to become irritated.

How Shoulder Impingement Happens

  • Repetitive lifting
  • Poor posture
  • Muscle imbalances

Symptoms

  • Sharp pain when reaching overhead or behind your back
  • A feeling of weakness or catching in the shoulder
  • Swelling in the front of the shoulder

When to Seek Help

If shoulder movements trigger discomfort, physical therapy can help improve posture, build strength, and reduce inflammation.

Tendinitis and Bursitis

Tendinitis is inflammation of the shoulder tendons, while bursitis affects the fluid-filled sacs (bursa) that reduce friction in the joint.

Why They Happen

  • Overuse during sports or repetitive tasks
  • Aging
  • Poor shoulder biomechanics

Symptoms

  • Aching pain at rest and during activity
  • Swelling or warmth around the joint
  • Limited range of motion

When to Seek Help

If rest and home care don’t improve symptoms within a week, targeted shoulder pain treatment can reduce inflammation and prevent chronic issues.

How Physical Therapy Helps Treat Shoulder Pain

Physical therapy plays a critical role in managing shoulder pain without the need for surgery or long-term medications. A customized treatment plan can help you move better, feel stronger, and return to daily activities with confidence. Here’s what you can expect:

  • Personalized evaluation to identify the root cause of pain
  • Hands-on techniques to reduce tension and improve mobility
  • Exercises that strengthen muscles and correct poor movement patterns
  • Postural training to prevent future flare-ups
  • Education to help you modify daily tasks and avoid reinjury
