If you’re dealing with heel or back-of-ankle pain — especially during walking, running or everyday activity — you may have Achilles tendonitis. At Feet for Life Centers, our podiatric specialists in St. Louis / Chesterfield provide advanced diagnostics and personalized non-surgical protocols to help you regain mobility, reduce pain and get back to the life you enjoy.
About Achilles Tendonitis
Understanding Achilles Tendonitis: Causes & Symptoms
The Achilles tendon connects your calf muscles to your heel bone and powers every step you take. When this tendon becomes irritated or inflamed from overuse, tight calf muscles, or poor footwear, the result is Achilles tendonitis — a leading cause of heel and ankle pain.
Common causes
- Sudden increase in activity or athletic training
- Tight calf muscles or limited flexibility
- Flat feet or high arches, which place extra strain on the tendon
- Unsupportive or worn-out shoes
Age-related changes that reduce tendon elasticity
If left untreated, this condition can progress to chronic degeneration (tendinosis) or even tendon rupture — making early podiatric care essential.

Non-Insertional Achilles Tendinopathy
This form of tendon irritation occurs in the mid-portion of the Achilles tendon, a few centimeters above where it attaches to the heel bone. It is most common in active adults and runners whose tendons experience repetitive stress.
Over time, the tendon fibers can become thickened, weakened, and painful—especially in the morning or after periods of rest.
Treatment focuses on controlled strengthening, stretching, and supportive footwear. In chronic cases, Extracorporeal Shock Wave Therapy (ESWT) may be used to stimulate healing and reduce inflammation.
Insertional Achilles Tendinopathy
This type affects the lower portion of the tendon, where it attaches directly to the heel bone. It often develops in people with tight calves, flat feet, or heel spurs.
Pain is typically felt where the tendon meets the heel, especially when climbing stairs or standing on tiptoe.
Treatment may include stretching, supportive footwear, and shockwave therapy to reduce inflammation at the attachment site. For pain directly at the heel, visit our Heel Pain Treatment page for related conditions like heel spurs or plantar fasciitis.
Heel Pain Treatment Options
1. Activity Modification and Footwear Support
Reducing repetitive strain on the tendon is essential for early recovery. We help patients adjust activity levels and recommend supportive, cushioned footwear that stabilizes the ankle and relieves heel pressure. For individuals with flat feet or arch imbalances, see our Flat Feet Correction page for more information on improving biomechanics that contribute to tendon stress.
2. Stretching and Strengthening Programs
Targeted calf stretching and eccentric heel-drop exercises are designed to restore flexibility and rebuild tendon strength. These programs are customized to your activity level and stage of healing—whether you’re walking, training, or returning to sports.
3. Extracorporeal Shock Wave Therapy (ESWT)
For chronic or difficult-to-heal Achilles pain, Extracorporeal Shock Wave Therapy (ESWT) delivers focused sound waves to the injured area. This increases blood flow, breaks down scar tissue, and stimulates the body’s natural healing response. It is a proven, non-invasive treatment for both insertional and non-insertional Achilles tendinopathy. Learn more about this therapy on our Shockwave Therapy for Heel Pain page.
Clinical research supports its effectiveness — see Stania M. et al., “The Effectiveness of Extracorporeal Shockwave Therapy for Midportion Achilles Tendinopathy,” J Clin Med 2023; 12(18):5868, PMC9382436.
4. Regenerative Medicine (PRP Therapy)
For recurring or advanced tendon injuries, platelet-rich plasma (PRP) therapy can help accelerate healing. This minimally invasive approach uses the body’s own growth factors to repair damaged tendon fibers and reduce inflammation.
5. Bracing and Support Solutions
Temporary heel lifts, braces, or ankle supports may be prescribed to offload stress on the tendon, promote proper alignment, and allow the tissue to heal naturally.
6. Surgical Repair (When Needed)
Surgery is only considered when conservative care has not provided adequate relief or when imaging confirms a significant tendon rupture. Our board-certified podiatrists perform minimally invasive surgical repair to remove damaged tissue and restore tendon integrity. Learn more about these procedures on our Foot Surgery page.

PEMF Therapy for Heel and Achilles Pain
At Feet for Life Centers, we also offer advanced recovery tools like PEMF (Pulsed Electromagnetic Field) therapy pads to support healing and improve circulation around the Achilles tendon and heel.
PEMF pads are lightweight, flexible electromagnetic devices that can be worn during the day or at night. These pads deliver gentle, low-frequency electromagnetic pulses that help increase blood flow, reduce inflammation, and stimulate tissue repair.
For patients with chronic Achilles tendonitis, ankle stiffness, or poor circulation, PEMF therapy can complement other treatments like shockwave therapy or physical rehabilitation. The result is improved recovery, less stiffness, and a faster return to pain-free movement — all without medication or invasive procedures.
Many patients find that using a PEMF pad consistently overnight or during rest periods helps keep blood flow active when the body would otherwise be still, supporting natural tissue healing.
Endoscopic Gastrocnemius Recession (EGR)
An Endoscopic Gastrocnemius Recession (EGR) is a minimally invasive procedure used to relieve tension caused by a tight calf muscle (gastrocnemius). When this muscle is too tight, it limits ankle motion and places excess strain on the heel, arch, and Achilles tendon, contributing to chronic heel pain or plantar fasciitis.
During the procedure, a small incision is made behind the calf, and a camera-guided instrument is used to gently release a portion of the tight tendon. This improves flexibility, restores normal motion, and reduces stress on the heel and foot.
EGR is typically performed on an outpatient basis and allows most patients to walk the same day in a protective boot, with a recovery period that is significantly shorter than traditional open surgery.
Frequently Asked Questions About Heel and Achilles Pain
How is Diagnosis of Achilles Tendonitis Peformed?
Achilles tendonitis is diagnosed through a physical examination and medical history. Most patients report pain at the back of the ankle that worsens with walking, running, or jumping—often after increasing activity or switching from cushioned shoes to thin-heeled footwear.
During the exam, your podiatrist will gently press along the Achilles tendon to check for tenderness, swelling, or thickening. The tendon may feel firm or have a small, painful bump. Patients often limp while barefoot but walk more comfortably in heeled or supportive shoes.
X-rays may be taken to rule out bone spurs or heel conditions, while MRI is reserved for suspected partial or complete ruptures that might require surgical repair.
For most patients, diagnosis is confirmed clinically, allowing treatment to begin right away. Learn more about our heel pain evaluation and treatment or advanced shockwave therapy options.
Pain at the back of the heel is often caused by Achilles tendonitis—inflammation or strain of the thick tendon connecting your calf muscles to your heel bone. It can develop from overuse, tight calves, flat feet, or worn-out shoes. If pain increases after activity or in the morning, it’s best to see a St. Louis foot and ankle specialist for an evaluation.
Morning heel pain is common with Achilles tendon or plantar fascia irritation. When tendons tighten overnight, that first step can stretch inflamed tissue and cause sharp discomfort. Stretching, supportive footwear, and shockwave therapy are proven ways to relieve this pain over time
Pain just above the heel or in the back of the ankle usually points to Achilles tendonitis, while pain on the bottom of the heel is more consistent with plantar fasciitis. Our podiatrists can pinpoint the cause with a quick physical exam and help prevent it from worsening.
If heel pain persists after rest and home care, treatments like targeted stretching, footwear changes, and Extracorporeal Shock Wave Therapy (ESWT) can help heal damaged tendon tissue. At Feet for Life Centers in St. Louis and Chesterfield, we specialize in non-surgical heel pain relief for conditions such as Achilles tendonitis and plantar fasciitis.
Most mild cases improve within a few weeks of rest and therapy. Chronic tendon pain may take several months to heal fully. Staying consistent with stretching and footwear support helps prevent recurrence.
You should schedule an appointment if your pain lasts more than a week, causes limping, or interferes with daily activities. Early treatment with a foot and ankle specialist can prevent chronic damage and get you back on your feet faster.
Yes. Wearing supportive shoes, stretching before activity, and avoiding sudden increases in exercise intensity can reduce strain on the Achilles tendon. Our podiatrists can design a personalized prevention plan to protect your feet long-term.
