Shoulder pain is one of the most common problems that our Physios see at our clinic in Haywards Heath. Understanding the most common shoulder pain causes is the first step towards fixing it.
Whether your pain started at the gym, from desk work, or for no clear reason, this guide will help you understand what’s going on and what to do next.
Why Shoulder Pain Is So Common
The shoulder is one of the most mobile joints in the body which is great for movement, but not always great for stability.
Unlike the hip, which is built for strength, the shoulder relies heavily on muscles and coordination to stay healthy. This means it’s more sensitive to:
- Repetitive movements (gym, work, sport)
- Poor posture or prolonged sitting
- Sudden increases in activity
- Weakness or poor control around the joint
In many cases, shoulder pain isn’t due to “damage,” but rather how the joint is being used and loaded over time.
5 Common Shoulder Pain Causes
Understanding the likely cause of your shoulder pain is the first step towards treating it effectively.
1. Rotator Cuff-Related Pain
This is by far the most common type of shoulder pain.
You might notice:
- Pain when lifting your arm (especially out to the side or overhead)
- Weakness or a feeling of “catching”
- Discomfort when lying on that side
At our clinic in Haywards Heath, this is the most common shoulder issue we see.
It often develops gradually and is usually linked to overuse, poor loading, or changes in activity levels.
2. Shoulder Stiffness (Early Frozen Shoulder)
This typically comes on more slowly.
You might notice:
- Increasing stiffness over time
- Difficulty reaching behind your back (e.g. putting on a coat)
- Pain at the end of movement
Early identification is important here, as management can differ from other types of shoulder pain.
3. Postural or Desk-Related Shoulder Pain
If you spend long periods sitting, especially at a desk, this can contribute.
Common features include:
- Tightness across the front of the shoulder
- Aching in the upper back or shoulder blade area
- Symptoms that worsen through the day
This is often more about muscle imbalance and sustained positions than injury.
4. Overuse or Gym-Related Injury
We commonly see shoulder pain linked to:
- Bench press
- Overhead lifting
- Poor technique or sudden increases in load
In many cases, it’s not the exercise itself; it’s how much, how often, and how well it’s being done.
5. Referred Pain from the Neck
Not all shoulder pain comes from the shoulder.
Signs it may be coming from the neck:
- Neck stiffness or discomfort
- Pain spreading down the arm
- Symptoms changing with neck movement
This is why accurate assessment is key—treating the wrong area won’t solve the problem.
How to Tell What Type of Shoulder Pain You Have
It’s not always possible to diagnose shoulder pain yourself, but a few patterns can help guide you:
- Pain when lifting your arm out to the side → often rotator cuff-related
- Global stiffness and reduced movement → could be early frozen shoulder
- Pain after sitting or desk work → often postural/muscle-related
- Pain with neck movement → may be referred from the neck
If you’re unsure, that’s completely normal—this is where a proper assessment makes a big difference.

Not Sure What’s Causing Your Shoulder Pain?
Many shoulder problems feel similar but need different treatment.
If you’re unsure what’s causing your pain—or the exercises aren’t helping—it’s worth getting it properly assessed.
We offer a free consultation, so you can talk things through and decide on the right next step.
3 Simple Exercises That Can Help Shoulder Pain
If your symptoms are mild and relatively recent, these exercises can be a good place to start.
1. Scapular Retraction
- Sit or stand upright
- Gently squeeze your shoulder blades back and down
- Hold for 5 seconds, repeat 8–10 times
👉 Helps improve posture and shoulder control
2. Wall Slides
- Stand facing a wall with your forearms on it
- Slide your arms upwards slowly
- Keep movements controlled and within comfort
👉 Encourages smooth shoulder movement
3. External Rotation with Band
- Keep your elbow by your side
- Rotate your forearm outwards against resistance
- Slow, controlled movement
👉 Targets the rotator cuff muscles
💡 Tip: Aim for little and often—5–10 minutes per day is enough to start making a difference.
Common Mistakes That Make Shoulder Pain Worse
A few common pitfalls we see:
- Pushing through pain at the gym
- Stopping movement altogether for too long
- Doing random exercises without a clear plan
- Ignoring technique and load management
The right balance is key: not too much, not too little.
Why Getting the Right Diagnosis Matters
Many shoulder conditions share similar symptoms—but require very different treatment approaches.
For example:
- Rotator cuff-related pain often responds well to exercise
- Frozen shoulder needs a different management approach
- Pain from the neck won’t improve if you only treat the shoulder
Getting the right diagnosis early helps:
- Avoid wasting time on the wrong exercises
- Speed up recovery
- Reduce the risk of the problem coming back
When to See a Physiotherapist for Shoulder Pain
While many cases improve with simple exercises, it’s worth getting assessed if:
- Pain has lasted more than 2–3 weeks
- You’re losing movement or strength
- It’s affecting your sleep
- It keeps coming back
- You’re not sure what the cause is
👉 If you’re experiencing multiple areas of stiffness or pain, our 10-Minute Daily Routine to Reduce Stiffness can be a helpful starting point.
