How does a GP diagnose bursitis or tendonitis from symptoms and examination?
A GP typically diagnoses bursitis or tendonitis through a combination of a detailed clinical history and a focused physical examination, often without the need for complex imaging. By assessing the location of the pain, the specific movements that trigger it, and the physical appearance of the joint, healthcare professionals in the United Kingdom can distinguish between different types of soft tissue inflammation. This diagnostic process is designed to rule out other conditions like fractures or arthritis while identifying the specific bursa or tendon that is affected. Understanding how a GP evaluates your symptoms can help you prepare for your appointment and ensure an accurate assessment of your joint health.

The role of clinical history in diagnosis
The diagnostic process begins with the GP asking detailed questions about when the pain started and how it behaves during the day. You will likely be asked if the pain came on suddenly due to an injury or gradually over several weeks, which helps differentiate between acute trauma and repetitive strain. The GP will also ask about your occupation, hobbies, and any recent changes in your activity levels. According to NHS guidance on joint pain, these details are vital for identifying the mechanical triggers that are characteristic of bursitis or tendonitis, such as pain that is worse after repetitive work or improves with rest.
Visual inspection and palpation
During the physical examination, the GP will first inspect the joint for visible signs of inflammation, such as swelling, redness, or bruising. In cases of superficial bursitis, like housemaid’s knee or student’s elbow, the diagnosis is often clear from the presence of a localized, fluid filled lump. The GP will then perform palpation, which involves gently pressing on specific points around the joint to identify areas of tenderness. Tendonitis usually causes pinpoint pain where the tendon attaches to the bone, whereas bursitis tenderness is often felt directly over the bursa sac itself.
Testing range of motion and strength
A key part of the examination involves moving the joint through its full range of motion, both actively (where you move the limb) and passively (where the GP moves it for you). The GP will look for a “painful arc,” which is a specific window of movement where the pain is most intense. They will also perform resisted muscle testing, where you are asked to push against the GP’s hand. If a specific movement causes sharp pain, it indicates that the tendon associated with that muscle is likely inflamed. This helps the GP pinpoint exactly which structure is causing the discomfort.
Specific orthopedic tests for soft tissues
GPs use specialized orthopedic tests to confirm a diagnosis of bursitis or tendonitis by recreating the mechanical stress that triggers the symptoms. For example, in the shoulder, they may use the Neer or Hawkins-Kennedy tests to check for impingement of the bursa or rotator cuff tendons. For the elbow, they may perform Cozen’s test to check for tennis elbow. These tests are designed to narrow the space around the joint or place the tendon under tension. If the test reproduces your typical pain, it provides strong clinical evidence for the diagnosis according to NICE clinical standards.
Distinguishing from other joint conditions
A critical part of the GP’s job is to ensure that the pain is not being caused by something more serious, such as a bone fracture or inflammatory arthritis. They will check the stability of the joint to rule out ligament sprains and look for signs of systemic disease, such as swelling in multiple joints or persistent morning stiffness. Unlike arthritis, which usually causes pain deep inside the joint and restricts all movements, bursitis and tendonitis pain is typically more localized to the outside of the joint and only affects specific directions of movement.
Screening for red flags and infection
The GP will also screen for “red flag” symptoms that might indicate a medical emergency. They will check for signs of septic bursitis, such as intense redness, extreme heat, or a break in the skin that could have allowed bacteria to enter the bursa. They will also ask if you have a fever, chills, or feel generally unwell. If any of these signs are present, the GP will prioritize ruling out a serious infection. Furthermore, they will check for any neurological symptoms, such as significant weakness or loss of sensation, which could suggest nerve compression or a complete tendon rupture.
When further investigations are required
Most cases of bursitis or tendonitis are diagnosed clinically, meaning no further tests are needed to start treatment. However, if the diagnosis is unclear or the symptoms do not improve with rest, the GP may order an ultrasound scan, which is very effective at visualizing fluid in a bursa or thickening in a tendon. Blood tests may also be ordered if the GP suspects an underlying condition like gout or rheumatoid arthritis. According to NICE guidelines, X-rays are rarely used for soft tissue diagnosis but may be requested if the GP needs to rule out bone spurs or calcium deposits within the tendon.
Conclusion
A GP diagnoses bursitis or tendonitis by carefully evaluating your symptom history and performing specific physical tests to identify the site of inflammation. By checking for localized tenderness, testing your range of motion, and screening for infection or red flags, they can create a tailored management plan without the need for immediate imaging. Most soft tissue conditions are accurately identified through this clinical approach, allowing for a faster start to recovery. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Do I need an MRI to diagnose tendonitis?
In the UK, an MRI is rarely the first step for diagnosis and is usually reserved for cases where surgery is being considered or if other treatments have failed.
Will the GP need to take a fluid sample from my joint?
Aspiration, or taking a fluid sample, is generally only done if the GP suspects the bursa is infected or if they need to check for gout crystals.
Can a GP tell the difference between a tear and tendonitis?
A GP can often distinguish between the two based on your muscle strength; a complete tear usually causes significant weakness that is not present in simple tendonitis.
How long does a typical GP joint examination take?
A focused musculoskeletal exam usually takes five to ten minutes within a standard GP consultation.
Should I take painkillers before my appointment?
It is often helpful to avoid strong painkillers immediately before your exam so the GP can accurately identify which movements trigger your pain.
What if my GP says they aren’t sure what it is?
If the diagnosis is unclear, your GP may refer you to a physiotherapist or a musculoskeletal specialist for a more detailed assessment.
Can I diagnose bursitis myself at home?
While you may recognize the symptoms, a professional diagnosis is important to rule out infections or other underlying conditions that require specific treatment.
