Achilles injuries rarely improve without proper treatment. Whether your pain started gradually or suddenly, knowing the difference between tendonitis and a rupture helps you avoid long-term problems.
If your pain feels similar to Heel Pain, it may be related.
Achilles tendonitis is inflammation caused by overuse or sudden activity increases. It’s common in runners, hikers, pickleball players, and weekend athletes.

An Achilles rupture is a partial or full tear of the tendon. It often happens during explosive movements or missteps.
