What Is Achilles Tendinitis?

The Achilles tendon is the largest tendon in the body, connecting your calf muscles to your heel bone and helping you walk, run, jump, and climb stairs. When this tendon becomes irritated, inflamed, or overworked, it leads to Achilles tendinitis — a common source of heel and lower-leg pain.

Many patients first notice pain after activity or stiffness in the back of the heel when getting out of bed. Left unaddressed, it can become persistent and interfere with everyday movement.

Symptoms of Achilles Tendinitis

Patients with Achilles tendinitis often experience:

  • Pain or aching in the back of the heel or lower leg
  • Stiffness or tenderness along the tendon
  • Pain that worsens with activity
  • Swelling or thickening of the tendon
  • Difficulty pushing off when walking or running

Understanding the Causes of Achilles Tendinitis

Achilles tendinitis typically results from repetitive stress to the tendon — often from running, jumping, or rapid increases in activity. Other common contributors include:

  • Sudden increases in exercise intensity
  • Tight calf muscles
  • Improper footwear
  • Changes in training surface or technique

Modern Treatment Options for Achilles Tendinitis

Shockwave Treatment for Plantar Fasciitis

Shockwave Therapy

Shockwave Therapy helps stimulate tendon healing and improve function by delivering focused acoustic energy to the injured area. This treatment is often recommended for patients with stubborn Achilles pain who want to return to activity safely and efficiently.

Shockwave Therapy

MLS Laser Therapy

MLS Laser Therapy supports faster recovery by reducing inflammation and enhancing cellular repair in injured tendon tissue. Many patients benefit from this comfortable treatment as part of a comprehensive plan to relieve Achilles pain and restore movement.

Custom Orthotics

Custom Orthotics

Custom orthotics help improve foot alignment and reduce strain on the Achilles tendon during walking, running, and daily activity. Providing targeted support and shock absorption, orthotics can play an important role in relieving pain and preventing the recurrence of tendon injuries.

When Should You See a Podiatrist for Achilles Tendinitis?

Consider scheduling an evaluation if:

  • Pain persists for more than a few days despite rest, stretching, or activity modification
  • Discomfort begins to limit walking, exercise, or daily activities
  • You notice swelling, stiffness, or tenderness along the back of the heel or ankle
  • Symptoms return repeatedly or worsen over time
  • Home remedies do not provide meaningful relief

Early evaluation can help prevent the condition from progressing and allow for more effective, non-surgical treatment options. Take the next step

FAQs: Achilles Tendinitis

Is Achilles tendinitis the same as a rupture?

No. Achilles tendinitis is an overuse injury that causes inflammation and pain in the tendon, while a rupture is a partial or complete tear of the tendon. A rupture is typically more severe and may require urgent medical treatment or surgery. A proper evaluation can help determine the cause of your symptoms.

How long does Achilles tendinitis take to heal?

Recovery time varies depending on the severity of the condition and the timing of treatment. Mild cases may improve within a few weeks, while more persistent or chronic cases can take several months. Following a structured treatment plan can help support healing and reduce the risk of recurrence.

Can I run or exercise with Achilles tendon pain?

Continuing to run or exercise through Achilles pain may worsen the injury and delay recovery. In many cases, modifying activity levels and addressing the underlying cause of tendon strain is important for healing. A podiatrist can help guide safe return-to-activity strategies.

Will custom orthotics help Achilles tendinitis?
Custom orthotics can help improve foot alignment and reduce excessive strain on the Achilles tendon during walking and running. For many patients, orthotics are an important part of a comprehensive treatment plan designed to relieve pain and prevent future flare-ups.
When should I see a doctor for Achilles tendon pain?
If pain persists for more than a few days, worsens with activity, or begins to limit your mobility, it may be time to seek evaluation. Early treatment can help prevent progression and support more effective non-surgical care.
What treatments are available for Achilles tendinitis?
Treatment options may include activity modification, stretching and strengthening programs, orthotics, and advanced therapies such as Shockwave Therapy or MLS Laser Therapy. Your podiatrist will recommend a personalized plan based on your condition and goals.
Can Achilles tendinitis come back?
Yes. Without addressing contributing factors such as biomechanics, training habits, or footwear, symptoms can recur. Preventive strategies and supportive treatments can help reduce the likelihood of future flare-ups.

The folks at Northeast Foot and Ankle are great! The staff were very kind and knowledgeable. The new patient process was very easy to do and they offered the ability to do it in advance on the portal. My appointment was on time and I was out in under 45 minutes.

Very happy I chose Northeast Foot and Ankle! Dr. Sartori and the entire staff are very attentive and knowledgeable. I had a bunion removed and from my initial appointment, through the surgery, and to the last follow up I always had a great experience. I highly recommend this group!

Jennifer

Total experience rates a 10. Dr. Baczewski was the epitome of what a medical professional should be. She offered a choice of options to alleviate my foot pain. Once I opted for surgery, the process went smoothly both in the surgery center and the office for post operative laser and follow up. The entire staff was welcoming, courteous, and highly trained. The facility was easy to access with ample parking. The online reminders for appointments was also a plus.
I would highly recommend Northeast Foot and Ankle.

Leslie

Both doctors are excellent practitioners who explain things upfront and do not try to upsell/push unnecessary services. I recommend laser treatments if you have persistent warts.
They also saved my baby sister’s life when the ER doctors wanted to send her home while she had a huge infection on her heel—one call from Sartori and she was admitted for three days and got the right treatment. She turned 21 this summer ☺️ these people care and do a great job!!
