Shoulder pain can turn daily life into a struggle – from putting on a jacket to getting a good night's sleep. The good news: most shoulder problems can be successfully treated, often without surgery. This comprehensive guide helps you understand your pain, shows you effective treatment options, and explains when you should see a doctor.

At a Glance

  • Shoulder pain is common – about 70% of all people experience it at least once in their lifetime

  • Most causes are harmless – muscle tension and overuse usually heal on their own

  • Movement is the best medicine – even when it initially hurts, gentle activity promotes healing

  • Surgery is rarely necessary – over 80% of shoulder pain improves with conservative therapy

  • Seek immediate medical attention for warning signs – sudden severe pain, numbness, or loss of strength are emergencies

Causes: Why Does My Shoulder Hurt?

The shoulder is the most mobile joint in our body – and that's exactly what makes it vulnerable. Unlike the hip, which is stable due to its ball-and-socket shape, the shoulder is primarily guided by muscles, tendons, and ligaments. This complex construction allows us to move our arm in all directions, but it also poses risks.

The Top 5 Pain Causes:

1. Muscle Tension and Overuse (approximately 40% of all cases)

  • Most common cause with desk work and one-sided strain

  • Typical: Pain in the neck-shoulder area

  • Often worsened by stress and poor posture

  • Good prognosis: Usually improves within days to weeks

2. Impingement Syndrome (Pinching Syndrome)

  • Tendons get pinched under the shoulder blade

  • Pain especially when lifting arm between 70-120 degrees ("painful arc")

  • Often affects people between 40-60 years old

  • Can lead to bursitis

3. Calcific Tendinitis (Calcium Deposits)

  • Calcium deposits in the tendons

  • Can trigger sudden, severe pain attacks

  • Frequently affects women between 30-50 years old

  • In many cases, the calcium dissolves on its own

4. Frozen Shoulder (Adhesive Capsulitis)

  • Painful movement restriction in all directions

  • Develops in three phases over 1-3 years

  • Often without identifiable cause

  • More commonly affects diabetics and women over 40

5. Rotator Cuff Injuries

  • Tears or inflammation of the stabilizing tendons

  • Common with overhead work or sports

  • Pain at night when lying on the shoulder

  • Ranges from small partial tears to complete ruptures

Rare but Important Causes:

  • Shoulder arthritis: Cartilage wear, usually in older people

  • Shoulder instability: After dislocation or with congenital connective tissue weakness

  • Nerve compressions: Radiating from the cervical spine

  • Systemic diseases: Rheumatism, polymyalgia rheumatica

  • Referred pain: From heart, lungs, or gallbladder

Where Exactly Does It Hurt? Pain Location Provides Important Clues

The exact location of your pain can reveal a lot about the cause. Here's a guide:

Pain on the Outside of the Shoulder

  • Most common cause: Bursitis or tendon irritation

  • Typical: Pain when lifting arm sideways

  • At night: Worsening when lying on the affected side

Pain at the Front of the Shoulder

  • Possible causes: Biceps tendon inflammation, anterior instability

  • Typical: Pain when reaching behind

  • Activities: Worsening with throwing motions

Pain at the Back of the Shoulder

  • Causes: Tense muscles, posterior capsule inflammation

  • Typical: Pain when moving arm forward

  • Accompanying: Often with neck tension

Pain Radiating Down the Arm

  • Causes: Nerve root irritation from cervical spine

  • Typical: Tingling, numbness, or weakness in the arm

  • Important: Neurological evaluation recommended

When Should I See a Doctor for Shoulder Pain?

Not every shoulder pain requires an immediate doctor visit. Here's clear guidance:

Go to the Doctor or Emergency Room Immediately for:

  • Accident injuries with visible deformity or inability to move

  • Sudden severe pain with loss of strength

  • Numbness or paralysis in the arm

  • Shoulder pain with chest pain (rule out heart attack!)

  • Fever and shoulder pain (possible joint infection)

  • Blue discoloration or cold feeling in the arm

See a Doctor Within a Few Days for:

  • Pain that doesn't improve after 1 week despite self-treatment

  • Increasing movement restriction

  • Night pain that disrupts sleep

  • Pain with swelling or warmth

  • Repeated pain attacks

Schedule a Doctor Visit for:

  • Chronic pain lasting over 4-6 weeks

  • Recurring complaints after exertion

  • If you're unsure or worried

  • For evaluation before planned sports activities

Which Doctor Is Right?

  • Family doctor: First point of contact, can usually help well and refer if needed

  • Orthopedist: Specialist for joint problems, for more complex complaints

  • Sports medicine doctor: For sports-related injuries

  • Rheumatologist: If inflammatory diseases are suspected

Diagnosis: How Does the Doctor's Examination Work?

The doctor will proceed systematically to find the cause of your shoulder pain.

Medical History Discussion:

  • How long have the pains existed?

  • What caused them?

  • How do they feel?

  • What makes them better or worse?

  • What medications are you taking?

Physical Examination:

  • Inspection: Swelling, redness, posture

  • Movement tests: Active and passive mobility

  • Strength tests of individual muscles

  • Special shoulder tests (e.g., impingement tests)

Imaging When Needed:

  • X-ray: Shows bone changes and arthritis

  • Ultrasound: Good for tendons, muscles, and bursae

  • MRI: Most detailed representation of all structures, usually only for unclear cases or before operations

A clear diagnosis isn't always possible immediately. Sometimes the doctor initially works with a suspected diagnosis and observes the progression.

Shoulder Pain Relief: What You Can Do, And What Therapy Options Are Available

What Can I Do Myself for Acute Shoulder Pain?

The first 48 hours are crucial. With the right measures, you can promote healing and relieve pain.

The RICE Method – First Aid for Acute Pain

  • Rest – Protect the shoulder, but don't immobilize completely

  • Ice – Cool for 15-20 minutes, several times daily

  • Compression – Light pressure with bandage (not too tight!)

  • Elevation – Support arm on pillow

Heat or Cold – What's Better?

Use Cold for:

  • Acute injuries (first 48 hours)

  • Swelling

  • Inflammatory processes

  • Sharp, bright pains

Use Heat for:

  • Muscle tension

  • Chronic pain

  • Stiffness

  • Dull, aching pains

Using Pain Medication Strategically

Ibuprofen (400-600mg)

  • Works as pain reliever and anti-inflammatory

  • Maximum 3 times daily

  • Take with food

Diclofenac Gel

  • Local application for superficial pain

  • Massage in 3-4 times daily

  • Fewer side effects than tablets

Acetaminophen

  • For ibuprofen intolerance

  • Less effective for inflammation

  • Maximum 4 times daily 500-1000mg

Important: Don't use pain medication for more than 5-7 days without medical consultation!

Movement – The Foundation of Healing

Even if it hurts initially: gentle movement is better than staying still!

Pendulum Exercises (Codman Exercises)

  • Support yourself with your healthy hand on a table

  • Let the painful arm hang loosely

  • Swing gently forward/back, then sideways

  • 5-10 repetitions, several times daily

Wall Climbing

  • Stand sideways to the wall

  • "Climb" up the wall with your fingers

  • Go as high as pain-free possible

  • Slowly come back down

These simple exercises keep the joint mobile and promote blood circulation.

Treatment: What Therapy Options Are Available?

Most shoulder pain can be treated without surgery. Surgical interventions are rarely necessary.

Conservative (Non-Surgical) Treatment:

  • Physical therapy: Movement therapy, strengthening, posture training

  • Medications: Pain relievers, cortisone injections for inflammation

  • Physical therapy: Heat, cold, electrical therapy

  • Alternative methods: Acupuncture, taping (research evidence still uncertain for some)

Surgical Treatment:

Surgery is only considered if conservative measures haven't helped after 3-6 months or for severe injuries.

  • Arthroscopy (joint endoscopy): Minimally invasive technique through small incisions

  • Open surgery: Necessary for larger repairs

  • Examples: Removal of calcium deposits, repair of torn tendons, widening of the shoulder roof

Healing Time: How Long Until It Gets Better?

Healing time depends heavily on the cause and your individual factors.

Typical Healing Times:

  • Muscle tension: A few days to 2 weeks

  • Bursitis: 2-6 weeks

  • Impingement syndrome: 6 weeks to 6 months

  • Rotator cuff tear: 3-6 months, after surgery 6-12 months

  • Frozen shoulder: 1-3 years (often even without treatment)

Factors That Influence Healing:

  • Your age (younger people heal faster)

  • General fitness and muscle strength

  • Accompanying diseases like diabetes

  • Following therapy recommendations

  • Occupational and sports stress

Patience is important – shoulder problems often need time to heal.

Prevention: How Can You Prevent Shoulder Pain?

Many shoulder problems can be avoided through simple measures.

Movement and Sports:

  • Regular, gentle movement (swimming, cycling)

  • Strengthening shoulder muscles, especially the rotator cuff

  • Overhead sports (tennis, handball) only with good technique

  • Don't forget to warm up before sports

Workplace and Daily Life:

  • Position screen at eye level

  • Take breaks every 30-60 minutes with shoulder circles

  • Carry heavy objects close to the body

  • Avoid or divide overhead work

Sleep and Recovery:

  • Don't sleep on the shoulder

  • Suitable pillow for good neck posture

  • Reduce stress (often leads to tension)

Frequently Asked Questions: Myths and Facts About Shoulder Pain

This depends on the cause:

  • Muscle tension: 3-7 days

  • Tendon inflammation: 2-6 weeks

  • Impingement: 6-12 weeks

  • Frozen shoulder: 1-3 years

  • After surgery: 3-6 months

Important: With proper treatment, healing time is often significantly shortened!

Can I continue working with shoulder pain?

In most cases yes, but with adjustments:

  • Use ergonomic aids

  • Take regular breaks
