The Basic Science of Tendons & Tendinitis
Tendonitis is an inflammation of a tendon. It is often caused by overuse or repetitive use of a tendon, which can lead to microtears in the tendon. These microtears can cause pain, swelling, and stiffness in the affected area.
The exact cause of tendinitis is not fully understood, but it is thought to be due to a combination of factors, including:
- Overuse or repetitive use of a tendon
- Age-related changes in the tendon
- Poor flexibility or muscle strength
- Certain medical conditions, such as rheumatoid arthritis
- Certain occupations or activities that involve repetitive movements
Tendonitis can occur in any tendon, but it is most common in the following areas:
- Achilles tendon (back of the heel)
- Patellar tendon (kneecap)
- Rotator cuff (shoulder)
- Wrist extensor tendons (back of the wrist)
- De Quervain’s tendonitis (swelling of the tendons that move the thumb)
The symptoms of tendinitis can vary depending on the severity of the injury. They may include:
- Pain
- Swelling
- Tenderness
- Stiffness
- Decreased range of motion
- Weakness
The treatment for tendinitis depends on the severity of the injury. Mild cases of tendinitis may improve with rest, ice, compression, and elevation (RICE). More severe cases may require physical therapy, medication, or surgery.
Here are some tips to prevent tendinitis:
- Warm up before exercising and cool down afterwards.
- Stretch regularly.
- Avoid activities that cause pain.
- Use proper technique when exercising.
- Strengthen the muscles that support the tendon.
- Lose weight if you are overweight or obese.
If you experience pain, swelling, or stiffness in a tendon, it is important to see a doctor to get a diagnosis and treatment. Early diagnosis and treatment can help to prevent the condition from getting worse.
