A massage gun is a handheld device that uses percussion, vibration, and sometimes heat to deliver therapy to the muscles. Massage guns are used to relieve muscle pain and soreness, reduce inflammation, and increase circulation. Massage gun use can help acute injuries where muscles are guarding an injured area, as well as with chronic pain syndromes. This technique is a natural way to decrease use of pain medication, injections, and other more invasive treatments (petersenpt.com). A percussive massage gun uses vibrations to warm the muscle tissue and increase blood flow to target areas to reduce pain, inflammation, and muscle soreness (Cleveland Clinic). Massage guns that are intended primarily for the treatment of pain are eligible for reimbursement with a tax-free healthcare account. Massage guns for general well-being or relaxation are typically not eligible and would require a Letter of Medical Necessity (LMN) from a medical professional to qualify.
