What Is Tendonitis?

The term tendonitis implies inflammation, but most chronic tendon pain involves tendinosis — degeneration of the tendon’s collagen matrix without significant inflammation. This distinction is clinically critical: anti-inflammatory interventions may temporarily reduce pain but do not address the failed healing process of degenerative tendon tissue.

Tendons commonly affected include the Achilles, rotator cuff (supraspinatus), patellar, proximal hamstring, iliopsoas, wrist extensors and flexors, and posterior tibialis. The underlying pathology and treatment principles are consistent: stimulate the failed healing response, load the tendon progressively, and address the mechanical factors driving the overload.

Common Symptoms

Patients presenting with tendonitis in Lee’s Summit commonly report one or more of the following:

Pain directly over the tendon
Pain with loading the tendon
Morning stiffness that eases with movement
Tenderness to direct pressure on tendon
Thickening or nodularity of the tendon
Weakness in the associated muscle
Pain with resisted contraction
Gradual onset without single traumatic event

If you are experiencing any of these symptoms, a chiropractic evaluation can identify the structural cause and determine whether conservative care is appropriate for your case.

Common Causes

Understanding what drives tendonitis is essential to lasting treatment — not just symptom relief:

  • Chronic mechanical overload
  • Sudden increase in activity
  • Poor technique in sport or work tasks
  • Muscular imbalances increasing tendon stress
  • Age-related collagen quality decline
  • Poor vascular supply (tendon avascular zones)
  • Fluoroquinolone antibiotic use (weakens tendon)
  • Metabolic conditions (diabetes, hypothyroidism)

Chiropractic Treatment for Tendonitis in Lee’s Summit, MO

Summit Chiropractic’s tendinopathy protocol is grounded in current tendon science. IASTM produces controlled microtrauma to the tendon, disrupting the disorganized collagen matrix and stimulating a fresh healing response — effectively restarting the failed repair cycle. Ultrasound therapy and soft tissue mobilization enhance tendon circulation.

The cornerstone of tendinopathy rehabilitation is eccentric loading: exercise where the tendon is loaded while lengthening, under controlled conditions. Decades of evidence support eccentric exercise as the most effective conservative intervention for common tendinopathies. A structured eccentric loading protocol is implemented, combined with correction of the biomechanical factors driving tendon overload.

Frequently Asked Questions

Are cortisone injections appropriate for tendonitis?
For acute symptom relief, possibly. Long-term, multiple studies show cortisone injections produce worse outcomes than conservative treatment for most tendinopathies, with potential for tendon weakening and increased rupture risk. Manual therapy and eccentric loading should be exhausted first.
How long does tendinopathy take to heal?
Tendon tissue heals slowly due to poor vascularity. With appropriate treatment, most patients see meaningful improvement in 6–12 weeks and full resolution in 3–6 months.
Can tendonitis turn into a tendon tear?
Yes. Degenerative tendinopathy weakens the tendon’s mechanical properties, increasing rupture risk under high load. This is particularly concerning for the Achilles and rotator cuff. Early treatment reduces this risk significantly.
