Tendonitis: Causes, Treatment & Recovery Timeline

What Is Tendonitis?

Tendonitis is inflammation of a tendon, the thick cord that attaches muscle to bone. It causes pain and tenderness near a joint. Tendonitis most commonly affects the shoulder, elbow, wrist, knee, and heel. It is usually caused by repetitive movements and responds well to rest and treatment.

Common Causes of Tendonitis

• Repetitive movements (sports, work)
• Sudden increase in activity
• Poor technique during exercise
• Aging (tendons lose flexibility)
• Improper ergonomics
• Tight muscles or poor flexibility

When to See a Doctor

See a doctor if pain persists more than two weeks despite rest, you can't move the joint, or there is significant swelling. Seek care if tendon pain interferes with work or daily activities.

Warning Signs That Need Immediate Attention

Frequently Asked Questions

How long does tendonitis take to heal?

Mild tendonitis typically heals in 2-4 weeks with rest and proper care. Moderate cases may take 6-12 weeks. Chronic tendonitis can take several months. Returning to activity too soon often delays recovery.

What is the best treatment for tendonitis?

Rest from the aggravating activity, ice, gentle stretching, and over-the-counter anti-inflammatories are first-line treatments. Physical therapy strengthens surrounding muscles. Cortisone injections help persistent cases.

Should I rest or exercise with tendonitis?

Avoid the specific activity causing pain, but don't be completely inactive. Gentle movement, stretching, and eccentric exercises (controlled lengthening) actually help tendons heal. A physical therapist can guide safe activity levels.

Can tendonitis become permanent?

Untreated tendonitis can become chronic tendinopathy, where the tendon degenerates rather than just being inflamed. Early treatment and proper rehabilitation prevent this. Most tendonitis resolves completely with appropriate care.

How much does tendonitis treatment cost?

Physical therapy costs $75-$250 per session. A cortisone injection costs $100-$300. An orthopedic visit costs $200-$500. MRI if needed costs $500-$3,000. OpenMyPro helps you find affordable orthopedic care.
