Whether your morning starts with a quick run or you just step off a curb at lunch, you must push off with your foot. Suddenly, you feel that sharp pain at the back of your heel. Pain in the Achilles tendon is annoying and, at some point, can even be debilitating. It is understandable to think that discomfort is tendon tightness, tendonitis, or a more serious tear. In the following, we will explain pain in the Achilles tendon.
What is the Achilles tendon?
The Achilles tendon is a strong and big tendon that connects the calf muscle to the heel bone. It is the strongest tendon and the largest in the human body. The Achilles tendon is strong because of how much force it must endure. Walking, running, jumping, and even climbing stairs are things that can quickly put a multi-ton load on the Achilles tendon.
From overuse and poor shoes to sudden changes in activity and tendon degeneration, the Achilles tendon can cause a lot of injury. Even the pain in the tendon can easily go from a dull early morning pain to an annoying and sharp pain.
Common Causes of Achilles Pain
Achilles pain can manifest differently for different causes. Here are the most common causes of Achilles pain:
1. Achilles Tendinitis (Tendinopathy)
Achilles Tendinitis (Tendinopathy) is the most common cause of Achilles pain. Tendinitis refers to the inflammation of a tendon and is generally caused by repetitive stress. Examples include runners who increase distance too quickly, weekend warriors who go from no activity to a full workout and individuals who spend all day working on their feet.
Achilles tendinitis (tendinopathy) causes burning or aching pain on the lower back of the leg. The pain is most severe in the morning and after the lower leg has been inactive. The lower leg is warm and swollen to the touch. Unlike tendon ruptures, the pain is constant.
Athletes and active individuals will experience tendinitis pain in other areas of the body. If this type of overuse pain is present throughout the body, a comprehensive musculoskeletal evaluation may be warranted.
2. Insertional vs. Non-Insertional Tendinopathy
"Insertional" vs. "non-insertional" tendinopathy describes the location of the pain. Insertional tendinopathy is pain at the heel bone and is often associated with the formation of a bone spur. Insertional tendinopathy is best felt when the individual is wearing footwear that has a heel that presses against the back of the heel.
Non-insertional tendinopathy is tendinopathy that affects the middle section of the tendon. Non-insertional tendinopathy is more prevalent in the 20 to 30 years old athletic population.
3. Partial Tear of Achilles Tendon
Partial tears are more serious than tendinitis. Partial tears involve disruptions to the fibers of the tendon that are either frayed or damaged. During activity, you may experience sharp pain that may subside to dull pain, or you may experience continued pain that, among other symptoms, may be confusingly similar to a muscle pull.
Weakness and the swelling of the tendon may also be present. Partial tears typically result from a single acute trauma but may also develop from chronic tendinopathy that has exacerbated the damage to the tendon.
Walking remains possible but is highly painful. The more detailed assessment of strength in the calf should show marked weakness in the affected calf muscle relative to the other side.
4. Rupture of the Achilles Tendon
Of all Achilles tendon injuries, this is the most dreaded. Complete rupture means the Achilles tendon has snapped. It is an injury of drama. Patients describe hearing or feeling a pop, sounding almost like a blunt kick or a gunshot to the back of the affected leg, but doing so without any form of physical contact. The pain is absolute, and most patients are unable to perform the act of standing on the toes or the push-off mechanism.
Most ruptures are confined to the so-called "weekend warriors" demographic: men aged between 30 and 50 years of age who have a propensity to play basketball, tennis, or racquetball but are not routinely prepared or sufficiently conditioned to play. However, ruptures of this tendon can occur in any patient of any demographic.
Signs of a Torn Achilles
This is a tough one. There are a few specific signs that differentiate Achilles tendinitis from a torn tendon.
The Thompson Test (Calf Squeeze Test): This is a very accurate and reliable test. In a prone position (face down), if a clinician squeezes your calf, and your Achilles tendon is healthy, your foot will move and go into plantar flexion (where your foot points down). If there is no movement in your foot, your Achilles is likely ruptured.
The Pop Sensation: Feeling or hearing a pop during activity is an indicator of possible rupture. Tendinitis will not cause an acute event of that manner.
Ability to Rise on Your Toes: While balancing next to a wall, if you are able to raise up on the toes of the affected foot, you likely do not have a ruptured tendon. If you are unable to perform that action or it is difficult, it is likely that a ruptured tendon or large tear has occurred.
Palpable Gap: If an Achilles tendon is completely ruptured, a clinician will likely be able to feel an actual gap in the tendon 4 to 6 centimeters above the heel.
Persistent Swelling and Bruising: Tendinitis may cause some swelling. Significant bruising that spreads toward the ankle and heel indicates a rupture. It is also worth noting that a complete tendon rupture may be less painful than severe tendonitis because there is no more tension in the tendon. Achieving a conclusive diagnosis requires imaging. An ultrasound or an MRI is ideal.
Who is most at risk?
Several factors increase the likelihood of Achilles injuries. One of them is age. Tendons become less flexible and more vulnerable to degeneration and tears as we age. A history of lateral ankle instability can change your biomechanics, causing excessive loading to your Achilles tendon. Other risk factors include:
- Flat feet and high-arched feet
- Tight calf muscles
- Sudden changes in your usual training
- Use of the antibiotic Fluoroquinolone (known to have side effects)
- Corticosteroid injections to the tendon
- Playing sports on hard surfaces
If you’ve had a stress fracture or have a history of shin splints, similar biomechanical factors may be putting your Achilles at risk.
Treatment: What Are Your Options?
1. Conservative (Non-Surgical) Treatment
For many cases of Achilles tendinopathy, conservative treatments are the first best option. This can include:
-Rest and activity modification — reducing or eliminating provocative activities
-Ice and anti-inflammatory measures—treating inflammation
- Heel lifts and changes in footwear—decreasing the strain on the tendon
- Physical therapy and eccentric strengthening—the "heel drop" protocol, which consists of eccentric calf exercises, is the best substantiated rehabilitation method for Achilles tendinopathy
- Platelet-Rich Plasma (PRP) injections—an option for persistent tendinopathy.
2. Surgical Treatment
Complete ruptures of the Achilles tendon and some large partial ruptures are almost always addressed with surgery. An Achilles tendon repair involves suturing the ruptured tendon to itself and is a type of open foot and ankle surgery. An extended rehabilitation protocol is required after this surgery.
Surgery for a complete rupture, versus a functional brace, will considerably shorten the recovery time. After the rehabilitation is completed, most people will be able to participate in recreational activities after 6 to 12 months.
When Should You Visit a Doctor?
Seek immediate attention when:
- You heard or felt a pop
- You can't bear weight
- You can't push off your foot
- Your heel and ankle are swollen or bruised
- Your pain lasts more than weeks without improvement
- You are an athlete and need a diagnosis
Delaying treatment for a rupture can allow the tendon ends to retract, making surgical repair more complex and prolonging recovery. Early evaluation matters.

Frequently Asked questions (FAQs)
Can I walk if my Achilles tendon is torn?
That depends on how much of your tendon is intact. Incomplete tears can be painful and result in a limp, but walking can still be possible. However, complete tears can make walking impossible since your calf can no longer help propel you forward. If you are having difficulty walking, especially after injuring your leg, we recommend seeking immediate help rather than waiting.
How long does Achilles tendinitis take to heal?
It can take weeks to months for Achilles tendinitis to fully heal, but the key is to address the pain and symptoms when they first occur. The average recovery time from mild to moderate tendinitis is considered to be around 6–8 weeks given that the injury is properly managed and you have had the necessary rehabilitation. Teammates and peers returning to sports can prolong your recovery time and worsen the condition of your tendinitis.
Am I likely to have surgery for an Achilles tear?
Not necessarily. Some partial tears and even some complete ruptures in older, less active patients may be treated using a functional brace. For active people, athletes, or patients with large complete ruptures, surgery is preferred to address the injury. For the best treatment in your case, a specialist will likely need to see you for an evaluation and may order an MRI.
What is the outcome if an Achilles rupture is ignored?
Not treating a completely ruptured tendon will eventually cause a gait that is unstable, and the ability to walk will be noticeably weakened. The ends of the ruptured tendon will retract and scar tissue will start to form over the rupture, but this will not return the tendon to its former state. Surgery to repair the tendon will be more difficult and have an even longer recovery the longer you delay seeking treatment. Out of most injuries, this is the one case where the time taken to seek treatment does affect the outcome significantly.
What about the possibility of an Achilles rupture if I have tendinitis?
Achilles tendon ruptures are often overlooked if Achilles pain is not chronic. Tendons that have chronic degeneration are more likely to rupture than healthy tendons. Chronic changes to the structure of a tendon can make it even more likely to be ruptured. Because of this, chronic Achilles pain should not be treated by pushing through the pain but rather evaluated and treated. To mitigate the possibility of rupture, tendinopathy should be treated as early as possible.
