- Tendonitis vs. Arthritis
- Related Resources
Rheumatic disorders, also called musculoskeletal diseases, are conditions that affect your bones, joints, and associated soft tissues such as muscles, tendons, bursae, and ligaments. These conditions often cause similar symptoms such as pain, swelling, and difficulty moving the affected part.
Due to similarities in their sites of occurrence and presentation, tendonitis and arthritis are often confusing for many people. Let us explore the major differences between these two common types of rheumatic conditions.
What is tendonitis and arthritis?
- Tendonitis is the inflammation of the tendon.
- A tendon is a connective tissue band or cord-like structure that connects a muscle to a bone.
What causes tendonitis?
The main causes of tendonitis include:
What causes arthritis?
The major causes of arthritis vary depending on the type. There are more than 100 types of arthritis and related conditions.
Causes of some of the main types include:
- Osteoarthritis: Occurs due to the wear and tear of the cartilage that cushions the joint. This may be caused by factors such as aging, obesity, or joint overuse.
- Rheumatoid arthritis: A type of chronic inflammatory condition in which the body’s immune system attacks its joints along with other tissues and organs. Certain factors such as genetics, female gender, obesity, and smoking may increase the risk.
- Psoriatic arthritis: Occurs in about 30 percent of people with psoriasis. The abnormal immune response that causes skin rashes also attacks the joint causing arthritis.
- Gout: A type of metabolic arthritis in which abnormal deposition of uric acid crystals in the joints causes joint inflammation.
Other causes of arthritis may include infection (septic arthritis) and joint injury.
What are the symptoms of tendonitis?
The main symptom is pain at and around the affected site. There may also be swelling of the area, and the part may be tender to touch.
- The pain gets typically aggravated on movement and gets relieved after rest and treatment.
- Pain may slowly build up in intensity or may be a sharp and severe type.
- Symptoms may come and go during the course of the disease.
What are the symptoms of arthritis?
Symptoms may vary depending on the type of arthritis. Characteristic arthritis symptoms include joint pain and swelling.
- The skin over the affected joint may appear red and the movement may be painful.
- There may be a grating sensation on moving the affected joint.
- Joint stiffness or reduced range of motion is also commonly seen.
How do you treat tendonitis?

How do you treat arthritis?
The treatment depends on the severity and cause of arthritis. It generally includes:
- Medications to reduce pain and inflammation such as nonsteroidal anti-inflammatory drugs and corticosteroids
- Topical creams or ointments (counterirritants)
- Disease-modifying antirheumatic drugs or biological agents
- Physical therapy
- Surgery may include joint repair, replacement, or fusion
Arthritis and tendonitis may be difficult to identify based on symptoms alone. Generally, tendonitis causes sudden or acute pain, whereas, in the case of arthritis, the pain is often chronic in nature.
Your doctor will take your detailed history, perform a physical examination and order certain imaging tests or blood work to identify the cause of your symptoms (tendonitis or arthritis).

What Are the Four Stages of Osteoarthritis?The four stages of osteoarthritis (OA) have been graded on the basis of X-ray findings. Higher grades indicate more severe signs of OA and the need for surgery. Grade 0 is the stage when the joint is healthy, Grade 1 is doubtful narrowing of the joint space with possible bone spurs, Grade 2 is the definite bone spurs with possible reduced joint space, Grade 3 is definite moderate joint space narrowing (at least 50%), and Grade 4 is the most severe stage.
