Tendon Rupture: Causes, Risks, and What You Can Do

A tendon rupture, a sudden tear in the tissue connecting muscle to bone. It often happens without warning, especially during sports or even everyday movements like stepping off a curb. This isn’t just a sprain or strain — it’s a complete or partial snap, and it usually means sharp pain, a popping sound, and immediate loss of function in the affected area. The Achilles tendon, the thick band at the back of your ankle that lets you push off when walking or running is the most common site, but shoulders, knees, and wrists can also be affected.

What makes some people more vulnerable? Age is a big factor — tendons lose elasticity over time. But it’s not just about getting older. NSAIDs, common painkillers like ibuprofen or naproxen can weaken tendons if taken long-term, especially in people already dealing with joint stress or reduced blood flow. Studies show that people using these drugs for chronic pain are at higher risk, even if they don’t feel any warning signs. Muscle weakness, poor flexibility, and sudden increases in activity level also stack the odds against you. And if you’ve had a prior tendon injury, your chances of another rupture go up significantly.

Many people don’t realize how quietly tendon damage builds up. You might feel stiffness in the morning, mild soreness after exercise, or a dull ache that goes away with rest — but those are red flags. Ignoring them can lead to a full rupture with no second chance. The good news? You can reduce your risk. Strengthening the muscles around your tendons, warming up properly, avoiding overuse, and knowing when to skip a workout can make a real difference. If you’re on long-term pain meds, talk to your doctor about alternatives that won’t compromise your tendons.

What you’ll find in the articles below are real, practical insights from people who’ve dealt with tendon injuries, medication risks, and recovery. You’ll see how NSAIDs might be quietly harming your tendons, how muscle weakness plays a role, and what steps actually help — not just quick fixes. No fluff. Just clear info that helps you protect what moves you.
