Pain in the Achilles tendon at the heel is commonly caused by the following: 1, Achilles tendon injury, if frequent jumping during sports, may lead to acute injury to the Achilles tendon, thus manifesting as Achilles tendon pain symptoms, the patient may have local swelling, and the pain symptoms are aggravated when pressure is applied. 2, posterior Achilles osteophytes, leading to repeated wear and tear in front of the Achilles tendon. The painful symptoms can be localized in the Achilles tendon. MRI of the Achilles tendon and lateral radiographs of the Achilles bone can reveal hyperplasia of the Achilles nodes. In this case, minimally invasive arthroscopic surgery is needed to remove the osteophytes and repair the damaged part of the Achilles tendon, which can completely solve the painful symptoms and restore the normal function of the Achilles tendon.
