Tendinitis: Types, Causes, and Treatment
Learn about the different types of tendinitis, common causes, symptoms, and effective treatment options to relieve pain and improve mobility.
Introduction
That nagging pain in your elbow after a weekend of gardening, the sharp ache in your shoulder after a new workout, or the stiffness in your Achilles tendon when you first get out of bed: chances are, you are experiencing tendinitis. This common condition, often mistaken for a simple strain, is a source of pain and frustration for millions, from elite athletes to office workers. But what exactly is it, and how can you effectively treat and prevent it? This comprehensive guide will demystify tendinitis, exploring its root causes, the most effective evidence-based treatments, and crucial prevention strategies. We’ll move beyond basic advice to give you a deeper understanding of how your tendons work and how to keep them healthy for the long haul.
What exactly is Tendinitis? More Than Just Inflammation
Tendinitis (also commonly spelled tendonitis) is the inflammation or irritation of a tendon, the thick, fibrous cord that attaches muscle to bone. This condition typically causes acute pain and tenderness just outside a joint. While the "-itis" suffix implies inflammation, recent research suggests that in chronic cases, the issue is often less about inflammation and more about degenerative changes in the tendon, a condition sometimes termed tendinosis. This is a crucial distinction, as it influences treatment approaches. Understanding this shift from an inflammatory model to a degenerative one helps explain why some cases persist despite anti-inflammatory treatments.
The Anatomy of a Tendon: Where the Problem Starts
To understand tendinitis, it helps to know what a tendon does. Tendons are made of strong, collagen-rich tissue designed to withstand significant tensile forces, transmitting the pull of the muscle to the bone to create movement. However, they have a relatively poor blood supply compared to muscles. This limited blood flow means tendons heal more slowly from micro-tears that occur during activity. When the rate of damage from repetitive use exceeds the rate of repair, these micro-tears accumulate, leading to the pain and dysfunction we know as tendinitis.

Common Types of Tendinitis and Their Tell-Tale Signs
Tendinitis can strike any tendon, but it most commonly affects a few specific areas. Recognising the type based on location can help you identify the cause.
Tennis Elbow (Lateral Epicondylitis)
Despite its name, you don't have to play tennis to get it. This affects the tendons on the outside of the elbow and is often linked to repetitive wrist and arm motions, like using a computer mouse, painting, or even cooking.
Achilles Tendinitis
This involves the tendon connecting your calf muscles to your heel bone. It's common in runners who suddenly increase their intensity or duration, and it causes pain along the back of the leg or above the heel, often worse in the morning.
Rotator Cuff Tendinitis
This causes pain in the shoulder, often felt as a dull ache deep in the joint, which can worsen when you reach overhead or try to sleep on the affected side. It's prevalent among painters, carpenters, and swimmers.
De Quervain's Tenosynovitis
This affects the tendons on the thumb side of the wrist. Pain is triggered by grasping something or turning the wrist, often described as a "catch" or "snapping" sensation. New parents often experience it from repeatedly lifting their baby.
Golfer's Elbow (Medial Epicondylitis)
Similar to tennis elbow but affecting the inner side of the elbow. It's associated with repetitive gripping motions.
The Primary Culprits: What Causes Tendinitis?
The development of tendinitis is rarely due to a single factor but rather a perfect storm of circumstances.
Repetitive Strain: The Most Common Trigger
The number one cause is repetitive motion. When the same action is performed repeatedly, it places sustained stress on a specific tendon. Think of a baseball pitcher throwing a ball, a cashier scanning items, or a programmer typing code for hours. These repetitive motion injuries account for the vast majority of cases.
Sudden Injury and Overload
A sudden, sharp movement or lifting something heavy can cause an acute tendon injury that develops into tendinitis. This is often the "straw that breaks the camel's back" on a tendon already weakened by minor, unnoticed repetitive stress.
The Role of Age and Underlying Conditions
As we age, our tendons naturally lose elasticity and become less tolerant of stress, making people over 40 more susceptible. Certain systemic diseases like rheumatoid arthritis or diabetes can also increase the risk of developing tendon pain.
How is Tendinitis Diagnosed?
If you suspect tendinitis, a proper diagnosis is key to effective treatment.
The Physical Examination: Palpation and Movement Tests
A doctor will typically begin by discussing your symptoms and medical history. They will then physically examine the area, pressing on the tendon to locate the precise point of tenderness and asking you to move the affected limb in specific ways to see which motions trigger the pain.
Imaging Tests: Ultrasound and MRI
While often not necessary for straightforward cases, imaging can rule out other conditions. An ultrasound is excellent for visualising soft tissues like tendons in real-time, showing inflammation and tears. An MRI provides highly detailed images of both bones and soft tissues and is used for assessing the severity of the damage, especially if surgery is being considered.
Effective Treatment Strategies for Tendinitis
Most cases of tendinitis respond well to conservative, non-surgical treatments. The goal is to relieve pain, reduce inflammation (if present), and promote tendon healing.
First-Line Defence: The R.I.C.E. Method
The immediate go-to treatment for acute tendinitis is R.I.C.E.:
Rest: Avoid activities that aggravate the pain. This doesn't mean complete immobilisation, but rather relative rest.
Ice: Apply ice packs to the area for 15-20 minutes at a time, several times a day, to reduce pain and swelling.
Compression: Use an elastic bandage or brace to help minimise swelling and provide mild support.
Elevation: If possible, elevate the affected area above the level of your heart to help reduce swelling.
Medications for Pain and Inflammation Management
Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help reduce pain and inflammation in the short term. For persistent pain, a doctor may recommend a corticosteroid injection, which delivers powerful anti-inflammatory medicine directly to the site. However, these are used sparingly as they can, in rare cases, weaken the tendon over time.
Physical Therapy and Rehabilitation Exercises
This is the cornerstone of treating and preventing recurrent tendinitis. A physical therapist can teach you specific exercises to gently stretch and strengthen the affected muscle-tendon unit. Eccentric exercises, which involve lengthening a muscle under tension, have been shown to be particularly effective for conditions like Achilles tendinitis and tennis elbow.
Advanced Treatment Options: Injections and Surgery
For cases that don't respond to conservative measures after several months, other options like platelet-rich plasma (PRP) injections, which use your own blood to promote healing, may be considered. Surgery is typically a last resort to remove damaged tissue or repair a severely torn tendon.
Can You Prevent Tendinitis? Proactive Measures to Take
Prevention is always better than cure, especially with a condition as stubborn as chronic tendonitis.
Proper Technique and Ergonomics
Whether you're lifting weights, playing a sport, or working at a desk, using the correct form is paramount. An ergonomic assessment of your workspace can prevent repetitive strain injury in the wrists and shoulders. A sports coach or trainer can ensure your athletic technique isn't putting undue stress on your tendons.
The Importance of Gradual Progression and Cross-Training
Avoid doing too much, too soon. Gradually increase the intensity, duration, or frequency of your activities. Incorporate cross-training, mixing different types of activities to avoid overstressing the same tendons day after day.
Strength and Flexibility: Your Best Defence
A consistent routine of strength training builds resilient muscles that can better handle load, taking stress off the tendons. Likewise, regular stretching improves flexibility and maintains the range of motion in your joints, protecting the tendons from excessive strain.
When to Seek Professional Help
While mild tendinitis can often be managed at home, it's crucial to consult a doctor if:
The pain is severe or doesn't start improving after a week of self-care.
The joint appears deformed, swollen, or red.
You experience a sudden "popping" sensation or cannot move the joint at all.
The pain is accompanied by fever, which could indicate an infection.
Conclusion
Tendinitis is a common but often misunderstood condition. It's not just a simple inflammation; it's a signal from your body that a tendon has been overloaded and needs attention. By understanding the causes, primarily repetitive strain and sudden overload, you can take proactive steps to modify your activities and prevent it from occurring. Remember, effective treatment is a marathon, not a sprint. It requires patience, a commitment to rest and rehabilitation exercises, and knowing when to seek professional help. By listening to your body and respecting its limits, you can overcome tendinitis and return to the activities you love, stronger and smarter than before.

Frequently Asked Questions
What is the difference between tendinitis and tendonitis?
There is no medical difference; both spellings refer to the same condition. 'Tendinitis' is the more commonly used medical term, while 'tendonitis' is a frequent variant spelling. The core meaning, inflammation of a tendon, remains the same.
How long does it take for tendinitis to heal?
Recovery time varies greatly. Mild cases may resolve within 2-3 weeks with proper care. More severe or chronic cases can take several months to heal completely. Adhering to a physical therapy regimen is critical for a full recovery and preventing recurrence.
Is it better to ice or heat tendinitis?
The general rule is to use ice for acute injuries (first 48-72 hours or when there is swelling and sharp pain) to reduce inflammation. Use heat for chronic pain (after the initial swelling subsides) to relax tight muscles, improve blood flow, and ease stiffness. Never apply heat to a swollen area.
Can tendinitis go away on its own?
Mild cases can sometimes resolve with rest and activity modification. However, without addressing the underlying cause (like poor technique or muscle weakness), it is very likely to return. Proactive treatment ensures proper healing and reduces the risk of it becoming a chronic issue.
What happens if tendinitis is left untreated?
Untreated tendinitis can lead to a more debilitating condition called tendinosis, where the tendon structure degenerates and weakens. It also increases the risk of a tendon rupture, a complete tear that often requires surgical repair. Early intervention is always best.
