Morning shoulder pain can restrict the individual’s ability to move their shoulder freely, which can impede daily activities such as getting dressed, reaching for items, or performing routine tasks. The pain and discomfort may reduce the individual’s ability to focus and concentrate on work or daily responsibilities, potentially impacting productivity.

So, looking for ways to alleviate and prevent shoulder pain is important to improve one’s quality of life. In this article, we will explore the possible reasons why you may have a sore shoulder after waking up and discuss effective treatments to alleviate the pain.

Possible Reasons Why You Have a Sore Shoulder

There are several potential reasons why someone may experience sore shoulders. Here are some common causes:

Improper Sleep Position

One of the most common reasons for shoulder pain from sleeping is an improper sleeping position. When we sleep, our bodies should be properly aligned to avoid putting excessive pressure on our joints. However, many of us unknowingly adopt positions that strain our shoulders.

Sleeping on your side with your arm tucked under your head or sleeping on your stomach with your arm extended can lead to neck and shoulder pain.

Rotator Cuff Tendinitis

Rotator cuff tendinitis, also referred to as shoulder impingement syndrome, is a medical condition that occurs when the rotator cuff tendons become inflamed or irritated. This inflammation can lead to pain and discomfort, particularly during overhead arm movements.

The inflamed tendons can become pinched or impinged between the bones of the shoulder, particularly the acromion (a bony projection of the shoulder blade) and the head of the humerus (the upper arm bone), leading to pain and restricted movement.

Rotator cuff tendinitis can lead to weakness and instability in the shoulder, affecting the ability to perform routine tasks and activities that involve the use of the arms.

Rotator Cuff Tear

A rotator cuff tear refers to a partial or complete tear of one or more of the tendons that comprise the rotator cuff muscles in the shoulder. This type of injury can lead to significant shoulder pain and functional impairment.

A rotator cuff tear involves damage to the tendons that attach the rotator cuff muscles to the upper arm bone. This disruption can cause pain and discomfort, particularly during shoulder movements and at rest.

If left untreated, a rotator cuff tear can result in persistent or chronic shoulder pain, potentially leading to the development of secondary shoulder conditions such as arthritis or bursitis.

Scapular Dyskinesis

Scapular dyskinesis refers to an abnormal movement or positioning of the shoulder blades (scapulae) during shoulder motion. This condition is often associated with joint and muscular imbalances, leading to dysfunctional shoulder blade movement patterns.

Imbalances in the muscles surrounding the shoulder blades can result in altered force distribution and coordination during shoulder movements, contributing to pain and dysfunction. Improper positioning of the shoulder blades can also compromise the stability of the shoulder joint, leading to increased vulnerability to shoulder injuries and pain during movement.

Frozen Shoulder

Frozen shoulder, also known as adhesive capsulitis, is a condition characterised by stiffness and pain in the shoulder joint. It typically develops gradually and progresses through three stages: freezing, frozen, and thawing.

A frozen shoulder leads to progressive stiffness and limited range of motion in the shoulder joint, resulting in pain and discomfort during movement. The pain and stiffness associated with a frozen shoulder can significantly impact the individual’s ability to perform daily activities and may lead to a decreased quality of life.

Without appropriate treatment, such as frozen shoulder physiotherapy, a frozen shoulder can lead to persistent or chronic pain, affecting the individual’s overall well-being and physical function.

Referred Pain

Referred pain is a phenomenon in which pain is perceived in an area of the body that is different from the actual source of the pain. This occurs because the nerves from various parts of the body can converge and share pathways in the spinal cord, leading to the brain interpreting the pain as originating from a different location than its actual source.

Certain heart conditions, such as a heart attack or angina, can cause referred pain to the shoulder, often the left shoulder, due to the shared nerve pathways.

Referred pain from the neck or upper back, which can stem from conditions such as cervical spine disorders or muscle strain, may also be perceived as shoulder pain due to the interconnected nerve pathways.

Diagnosing the Underlying Cause of Your Shoulder Pain

When experiencing shoulder pain after waking up, it is important to seek a proper diagnosis from a healthcare professional. They will perform a thorough examination and may order imaging tests, such as X-rays or an MRI, to identify the underlying cause of your shoulder pain. Once the cause is determined, an appropriate treatment plan can be developed.

Ways to Relieve Shoulder Pain

There are several methods for your shoulder pain relief. Here are some effective ways to alleviate discomfort:

Lifestyle Modifications

Making certain lifestyle modifications can significantly reduce shoulder pain. Here are some changes in your lifestyle that you may incorporate into your daily life if you experience shoulder pain:

Stay Active

Although it may be tempting to rest a painful shoulder, staying active within your pain tolerance is important for maintaining joint mobility and preventing muscle stiffness. Engaging in low-impact exercises, such as swimming or walking, can help keep the shoulder joint mobile without exacerbating the pain.

Be Mindful of Your Sleeping Position

Sleeping on your back with proper support under your neck and knees is generally the most recommended and considered to be the optimal sleeping position. If you prefer sleeping on your side, place a pillow between your knees and another one to support your arm and keep your shoulder in a neutral position.

Aim for Better Quality of Sleep

Getting a good night’s sleep is essential for overall health and healing. Setting a consistent sleep routine, optimizing your sleep environment for comfort, and engaging in relaxation practices prior to bedtime can enhance the quality of your sleep. Avoiding caffeine and electronic devices close to bedtime can also contribute to better sleep.

Anti-Inflammatory Medications

Pain relief and anti-inflammatory medication are a decision for your doctor or pharmacist. Anti-inflammatory medications act by inhibiting the production of prostaglandins, which are natural chemicals in the body that promote inflammation, pain, and fever.

This pain relief can enhance mobility and functional capacity in the affected shoulder.

Massage Therapy

Massage therapy can aid in alleviating muscle tension and enhancing blood circulation to the impacted area, thereby fostering healing and diminishing discomfort. A qualified massage therapist can target specific muscles and fascia in the shoulder region to alleviate the shoulder and arm pain that you’re experiencing. However, it is crucial to consult with a healthcare professional or physical therapist to ensure that massage therapy is appropriate for your specific condition.

Physiotherapy

Shoulder pain physiotherapy plays a crucial role in the treatment of shoulder pain.

A qualified physiotherapist like our clinicians at Phoenix Rehab can develop a personalised exercise program that targets the underlying cause of your shoulder pain. As part of this program, the physiotherapist may make the patient perform different activities, such as stretching and muscle strengthening exercises to improve shoulder stability and flexibility.

Physiotherapists can also provide hands-on techniques, such as joint mobilization or soft tissue techniques, to further alleviate pain and promote healing.

Steroid Injections

In cases where shoulder pain persists despite conservative treatments, such as rest and physical therapy, your doctor may recommend a corticosteroid injection to treat shoulder pain. These injections can provide temporary relief by reducing inflammation in the shoulder joint. However, it’s important to note that the effects of steroid injections are not long-lasting, and repeated injections can have side effects.

When to See a Doctor

While many cases of shoulder pain can be managed with conservative treatments, there are instances when it is crucial to seek medical attention. If your shoulder pain is severe, persists for more than a few weeks, or is accompanied by other concerning symptoms, such as weakness or numbness, enduring shoulder pain shouldn’t be an option, and you should consult a healthcare professional. They can provide a thorough evaluation, accurate diagnosis, and appropriate treatment options.

Amazing experience with Phoenix Rehab, was assisted by Mavis. She’s very kind and professional and did thorough check on my wrist. I feel very comfortable during the process.

I went in for thermoplastic splint, and everything went smoothly. She was able to address my needs on my left wrist sprain.

They were prompt with appointment process and inquiry. Also the clinic is very close to Tanjong Pagar MRT. I highly recommend!

Huge shoutout to Yuna Zhang from Phoenix Rehab for helping in my recovery from golfer’s elbow 🙌

I walked in with persistent elbow pain that was affecting workouts and everyday tasks, and Yuna immediately made me feel confident I was in the right hands. She took the time to properly assess my condition, explain the root cause, and tailor a treatment plan to my specific needs instead of using a one-size-fits-all approach.

What I really appreciated was how personalised every session felt. The exercises she gave me were practical, easy to follow, and actually worked. Within a short time, the pain reduced significantly and my strength and mobility improved much faster than I expected.

On top of that, the pricing is very reasonable and affordable, which made committing to recovery much easier.

Professional, knowledgeable, and genuinely caring — highly recommend Yuna at Phoenix Rehab if you’re dealing with hand-related sports injuries 💪

Final Words

Shoulder pain after waking up can significantly impact your daily life and overall well-being. By understanding the possible reasons behind your shoulder pain and implementing appropriate treatments, you can find relief and regain your mobility. With the right approach, there is usually a lot that can be changed once the cause is found.

Where are you with this right now?

1. It is settling on its own

Many shoulder problems settle over weeks to months. Night pain that slowly becomes less frequent, and reach that slowly returns, are the usual pattern. If you are reaching higher this month than last, and sleeping better, it is on the normal course. You do not need us for this, and we would rather say so.

2. It has stopped improving

You put your shirt on that arm first. The top shelf belongs to someone else now. You have stopped reaching behind you without thinking.

Reach comes back before strength does. A shoulder that goes overhead but cannot hold anything there is halfway, not finished. That is the gap worth measuring, and it is not measured by how you feel on the day.

The Stalled Recovery Review is three appointments over three weeks with the same therapist, because what a joint does under load cannot be read in one visit. The first finds what is limiting it. The next two measure how it responds. $690, nett, no GST, which is three appointments at $230.

3. You have had surgery, or you have a date

Recovery after an operation has a shape, and knowing which stage you are in tells you whether you are on it. See the Rotator Cuff Repair Recovery Program, or shoulder physiotherapy if you are not sure which applies to you.

All of it runs on the same four stages. The Phoenix Recovery Protocol explains what each stage works on and what you have to meet to move up. No referral needed to start.

Next step

Find out which stage you are in

Pain is the first thing to leave. Movement and strength are the last things trained back, and most people stop before that part is done. One Assessment and Treatment is a single 45-minute appointment at $230, nett, no GST. Your therapist finds what is actually limiting you, treats it in the same appointment, and you leave with your current stage and a written plan.
