Extracorporeal Shockwave Therapy
A patient guide to ESWT — a non-surgical option for stubborn tendon pain that uses acoustic waves, not electricity.
ESWT is a non-surgical treatment that uses high-energy acoustic waves to stimulate a biologic response in injured or painful tissue. Despite the name, it does not use electrical shocks — it delivers precisely controlled acoustic pressure waves through a handheld device on the skin. Treatment is done in the office and typically requires no injections, sedation, or downtime.
Conditions that may be appropriate
Recommendations are individualized based on your diagnosis, examination, and current evidence.
During treatment
Ultrasound gel is applied, and a handheld applicator delivers acoustic waves while intensity is adjusted for comfort and effectiveness. Most patients describe it as uncomfortable rather than painful. ESWT is designed to stimulate a gradual biologic response — some notice improvement within weeks, others over two to three months. Insurance coverage varies by diagnosis and plan; our office discusses anticipated costs beforehand.
After treatment & combining care
My clinical perspective
One of the most common misconceptions I encounter is that chronic tendon pain simply needs more rest. In reality, many chronic tendon conditions are not primarily inflammatory — they represent changes in the structure and function of the tendon over time.
“The goal is not simply to reduce pain — it’s to restore function and support a successful return to the activities that matter most to you.”
Common misconceptions
No — ESWT uses acoustic (sound) waves, not electrical current.
It works by stimulating gradual changes — improvement usually unfolds over weeks to months.
Pain and tissue recovery don't always move together — keep up rehab after symptoms improve.
Exercise remains essential — ESWT complements a structured rehab program, it doesn't replace it.
