Symptoms of Achilles Tendinitis

Posted on July 25, 2022 in Achilles Tendinitis by Dr. Erik Nilssen

Achilles tendinitis happens when your tendon that connects your heel to the back of your leg becomes painful and swollen close to the bottom of your foot. This tendon, called the Achilles tendon, enables you to push your foot down when you walk, run, or perform other movements.. You use this tendon during activities, such as jumping and running.

Participating in high impact, strenuous exercise, like running, is a common cause of Achilles tendinitis. If you ignore this condition, it can result in you rupturing or tearing your tendon. If you rupture or tear this tendon, it is crucial that you seek treatment immediately.


Pain in your tendon that gradually builds up over time is a common symptom of Achilles tendinitis. The pain you experience with this condition often starts off mild (feels more like an ache) above your heel or in the back of your leg after a sports activity, like running. More serious pain can occur after prolonged sprinting, running, or stair climbing.

Other Achilles tendinitis symptoms include:

  • Pain and stiffness along your Achilles tendon upon waking in the morning.
  • Activity worsens the pain you experience on your tendon or back of your heel.
  • Your tendon becomes thick.
  • You end up with a bone spur.
  • You end up with swelling which gets worse with activity.

Since this condition is degenerative and often changes the structure of the tendon, as well as causes extreme pain, tearing, and serious damage, it is essential that you recognize and pay attention to your symptoms and see a doctor immediately.


There are numerous reasons you could develop this condition. It’s easier to avoid some causes than others, but either way, getting a diagnosis early can help prevent severe injury. This condition is chronic and happens usually from overuse.

Typically, it comes on gradually with time until you experience constant pain and activity or exercise becomes too painful for you to continue. If you experience an achy or sore Achilles tendon, it’s important that you rest it right away.

Lack of flexibility in the muscles of your calves is another big contributor of this condition. This causes your muscle to shorten resulting in more tension in your tendon. Another contributor is overuse and sudden increase in activities like speedwork, training mileage, and hill running. An injury to the Achilles tendon is slow to heal due to a limited blood supply. Recognizing signs like aches, tension, or tenderness early on is an essential part of treating tendon injuries.


Self-care measures can help tendinitis. However, if your symptoms and signs are persistent or severe, your doctor can recommend other options of treatments. If you are taking naproxen, ibuprofen or other over-the-counter pain medications and that is not enough, stronger medications might be prescribed for you to relieve pain and reduce inflammation. Other treatments offered by an ankle and foot center include physical therapy, orthotic devices, or surgery.

10 Questions to Ask Your Personal Injury Specialist

Orthopedic injuries can cause pain that lasts a lifetime. While many people associate orthopedics injuries with old age or contact sports, they are just as often caused by traumatic injuries resulting from car wrecks and on-the-job accidents. Accidents can cause a variety of orthopedic injuries, ranging in severity from mild to life-threatening. While you may seem fine in the immediate aftermath, the surge of adrenaline generated by your body during an accident can actually cover up serious but invisible injuries. These hidden injuries can surface in the days or weeks following an accident, and, if left untreated, they can lead to years of pain and suffering.

Personal Injury: Benefits of Going to an Orthopedic Specialist Versus the ER

Personal injury is a legal term for any injury to the body or mind of an individual, as opposed to damage to property.
