Achilles Tendonitis

Achilles tendonitis — pain, stiffness, and swelling in the Achilles tendon — is a serious overuse injury that requires more than rest and ice. Our regenerative approach heals the tendon while chiropractic care corrects the biomechanical cause.

What Is Achilles Tendonitis?

Achilles tendinopathy ranges from reactive tendinopathy (early, reversible) to degenerative tendinosis (advanced, with structural disorganization of collagen). The Achilles tendon, the largest and strongest tendon in the body, undergoes progressive degeneration from repetitive overloading — particularly when pelvic imbalance and overpronation create abnormal medial column loading that torques the Achilles with each step. Untreated Achilles tendinopathy progresses to rupture risk. Regenerative therapies combined with biomechanical correction of the underlying cause provide the most effective path to tendon recovery.

Common Symptoms

Pain and stiffness at the back of the heel and lower leg
Morning pain that eases with movement ('warm-up phenomenon')
Tendon thickening, swelling, or nodule formation
Pain with running, jumping, or stair climbing
Tenderness 2–6 cm above the calcaneal insertion
Crepitus (squeaking) with ankle movement

Common Causes & Contributing Factors

Overpronation creating torsional stress on the Achilles
Pelvic imbalance altering lower extremity biomechanics
Sudden increase in training load without adequate tendon adaptation
Tight gastrocnemius and soleus increasing Achilles tendon load
Prior fluoroquinolone antibiotic use weakening tendon collagen
Poor footwear (low drop to high drop change too rapidly)

The Pura Vida Protocol: Chiropractic Care for Achilles Tendonitis

Dr. Foss addresses Achilles tendinopathy from the kinetic chain up. Pelvic leveling and lumbar corrections remove the upstream forces driving overpronation and asymmetric tendon loading. Calcaneal and ankle joint adjustments restore normal hindfoot mechanics. Myofascial release of the gastrocnemius and soleus reduces tendon compressive loading. Regenerative therapies are applied directly to the Achilles tendon to stimulate collagen synthesis, restore tendon architecture, and reduce the risk of progression to rupture.

At Pura Vida Chiropractic, Dr. Foss uses Sacro-Occipital Technique (SOT) — a gentle, category-based system that addresses the spine, pelvis, and craniosacral rhythm as one integrated unit. SOT restores proper biomechanics, reduces nerve interference, and creates the neurological environment your body needs to heal itself.

Advanced Therapies We Combine With Chiropractic

For many patients, combining spinal correction with regenerative therapies produces faster and more lasting results. Depending on your condition, Dr. Foss may incorporate one or more of the following:

Shockwave Therapy

High-energy acoustic waves penetrate deep into tissue to break up calcifications, stimulate collagen production, and accelerate the body's natural repair process — all without surgery or downtime.

SoftWave Therapy

Patented unfocused shock waves spread over a broad treatment area to reduce inflammation, increase blood flow, and activate stem cells — promoting cellular regeneration and long-term pain relief.

Class IV Laser Therapy

Photobiomodulation with a 10–15W Class IV laser delivers therapeutic light energy deep into tissue, reducing inflammation, blocking pain signals, and speeding healing at the cellular level.
