Shoulder Pain After Sport: What Your Physio Would Tell You in Consultation

Your shoulder has been hurting since yesterday's session. Or for the past six months. You've tried rest, ice, and ibuprofen. It eases, it comes back. This is not an inevitable price of sport. It is a mechanical signal. Here is how to read it.

Why Your Shoulder Hurts After Training

Rotator cuff tendinitis and shoulder impingement syndrome account for the vast majority of post-training shoulder pain. These structures deteriorate silently before the pain becomes a real obstacle to practice.

Anatomy reminder: the rotator cuff

A group of four tendons (supraspinatus, infraspinatus, teres minor, subscapularis) that stabilise the humeral head in its socket and enable the shoulder's large range of motion.

The rotator cuff and its vulnerabilities

These four tendons act like guy-wires. They hold the humeral head firmly in its cavity. Without them, the shoulder loses all precision.

Repetitive movements create invisible micro-lesions that accumulate session after session. Age reduces tendon resilience: vascularisation decreases, slowing recovery. Training must be adapted accordingly.

Shoulder impingement explained simply

The space beneath the acromion can narrow abnormally. This pinching irritates the bursa. You feel this discomfort during a lateral arm raise — a classic in weight training, swimming, and tennis.

Repeated overhead movements stress this space excessively. Without changing your habits, the pain becomes chronic.

Joint instability in throwing sports

Handball, baseball, and volleyball impose extreme demands on the joint capsule. Ligaments stretch during rapid throwing movements. This capsulo-ligamentous distension undermines overall stability.

Chronic shoulder instability often results from ligamentous laxity not compensated by targeted strengthening of the rotator muscles.

Identifying Your Exact Type of Pain

Muscle soreness or deep tendinitis?

Deltoid soreness is typically diffuse and superficial. A joint problem feels internal and very localised.

Timing is a key indicator. Classic muscle soreness appears about 24 hours after exercise. A tendon lesion can be immediate or wake you during the night — the latter is significant.

Signs that require a prompt consultation

Sudden loss of strength, pain radiating toward the hand or fingers, persistent night pain, mechanical locking of the joint. Do not ignore these signals.

Assessing the impact on daily life

Observe difficulties when dressing, combing your hair, or carrying a bag. These simple gestures reveal the real extent of the problem. If putting on a coat becomes an ordeal, the time to seek help has arrived.

Immediate Steps to Reduce Inflammation

Rest and cold application protocol

Apply cold for 20 minutes, three times a day, with a cloth between the ice and skin. Complete rest is not ideal: gentle movement maintains tissue health. Simply avoid painful movements.

Ice application on shoulder
The emergency protocol
  1. Immediate rest of the joint (not complete inactivity).
  2. Cold for 20 minutes, 3×/day.
  3. Gentle, progressive movement below the pain threshold.
  4. Ergonomic adjustments: move your mouse closer, carry bags against your body, use a pillow under your armpit at night.

Adapting your daily habits

Move your mouse closer to avoid extending the arm. Carry bags against your body rather than at arm's length. Limit overhead movements: this position increases internal mechanical stress.

Sleep position

Sleep on the non-painful side with a pillow under the injured armpit. This neutral position promotes muscle relaxation and allows tissues to repair during the night.

Correcting Technique Errors in Your Training

Bench press and dips

On the bench press, flaring the elbows to 90 degrees strains the joint. Tuck them slightly toward the torso. With dips, descending too low violently stretches the capsule — respect your anatomical limits without sacrificing short-term performance.

The importance of scapular control

The shoulder blade serves as a stable base for the humerus. Without scapular stability, the shoulder compensates and inevitably suffers. Overly tight pectorals pull the shoulders forward and reduce the subacromial space. Strengthen your scapular fixators regularly.

Good scapular control
  • Fewer mechanical conflicts
  • Better load distribution
Poor scapular control
  • Rotator cuff inflammation
  • Chronic instability

Managing load to avoid overtraining

Progressive loading in shoulder rehabilitation
  • 10% rule: never increase volume or load by more than 10% per week.
  • Deload weeks every 4 to 6 weeks.
  • Monitor residual pain: any pain lasting more than 24 hours after a session signals overload.

When to See a Physiotherapist in Geneva?

Despite your efforts, professional expertise is sometimes essential to establish an accurate diagnosis and prevent a minor discomfort from becoming a lasting limitation.

Medical imaging

X-rays reveal bone and calcifications. Ultrasound analyses tendons in motion — often the most useful first-line investigation. MRI confirms suspicions of complex tendon rupture. Early diagnosis prevents serious complications.

Rehabilitation: the Jeremy Lewis approach

Manual therapy releases joint tension. Progressive strengthening follows — targeting the external rotators, which are often neglected. In Geneva, I apply Jeremy Lewis protocols, recognised as among the most reliable for shoulder rehabilitation.

Exercises integrated into my practice:

  • L-Fly with low pulley
  • External rotations with resistance band
  • Serratus anterior work for scapular stabilisation

Expect 3 to 6 months of consistent work for a durable recovery. Healing does not support shortcuts.

Limits of self-medication

Repeated corticosteroid injections weaken tendons over time. Use them sparingly. Surgery (arthroscopy) remains a last resort, reserved for complete ruptures or major anatomical conflicts after rehabilitation has failed.

Prevention for a Lasting Return to Sport

Sport-specific warm-up

Cardio is not enough. Your joints need targeted preparation before each session:

  • Light rows to activate the lower trapezius
  • Internal and external rotations with resistance band
  • Progressive shoulder circles

Nutrition and hydration

A dehydrated tendon is a more fragile tendon. Drink regularly during sessions. Favour foods rich in vitamin C and protein, essential for tendon collagen synthesis.

Recovery tools

Tool Use Shoulder benefit Precaution
Massage gun Percussion therapy Relaxes the deltoid Avoid bony areas
Tennis ball Targeted pressure Releases trigger points Moderate pressure
Foam roller Myofascial release Improves flexibility Avoid acute areas
Ice Local cryotherapy Reduces inflammation Always use a cloth

These tools are useful but never replace professional advice. If pain persists, seek help.

Frequently Asked Questions

Why does my shoulder hurt after sport?

Most often, it is inflammation of the rotator cuff or shoulder impingement caused by repetitive movements or poor technique. It signals that your tendons are under more load than they can currently withstand.

How do I tell the difference between muscle soreness and tendinitis?

Muscle soreness is diffuse, superficial, and appears about 24 hours after exercise. Tendinitis is a deep, localised pain that can be immediate or wake you at night. Night pain is a serious inflammatory sign worth consulting about.

When should I see a physiotherapist for shoulder pain in Geneva?

If the pain lasts more than 10 days despite rest, if you lose strength, or cannot lift your arm sideways. Early consultation enables the right protocol to be put in place and prevents a passing discomfort from becoming a tendon rupture.

Can I keep training with a painful shoulder?

In some cases yes, by reducing load and avoiding painful movements. In others no, because continuing worsens the injury. This is precisely what a physiotherapy assessment establishes: an informed decision, not a blanket rule.
