Yes, shockwave therapy does produce side effects, though most are temporary and localized to the treatment area. Common reactions include redness, swelling, bruising, and soreness that typically resolve within 24–72 hours.

Shockwave therapy — radial ESWT specifically — works by generating pressure waves that stress tissue to trigger a healing response, so some post-treatment discomfort is part of the mechanism, not a malfunction. Most users experience a temporary increase in pain for one to three days after sessions, particularly early in a treatment course. More serious reactions such as nerve irritation, petechiae (small skin hemorrhages), or prolonged swelling are less common and usually tied to excessive pressure settings or treating contraindicated areas. Radial ESWT devices like Kalecope's Q60 or T800 allow bar pressure adjustment precisely to reduce this risk by starting at lower intensities.

  • Post-treatment soreness and redness typically resolve within 24–72 hours after a shockwave therapy session.
  • Temporary increase in localized pain is reported by a subset of users, most often during the first 1–3 sessions of a protocol.
  • Petechiae (minor skin hemorrhaging) can occur at settings above therapeutic need; radial ESWT devices like the Kalecope T800 address this via a 1–10 bar adjustable range.
  • Shockwave therapy is contraindicated over open wounds, bone growth plates, malignancies, and implanted devices — applying it to these areas significantly raises adverse risk.
  • Nerve or vascular tissue injury is rare but documented when shockwave is applied directly over major nerve trunks or arteries.

Safety Notes

  • Implanted devices and pacemakers: Never apply shockwave therapy near a pacemaker, implanted stimulator, or metal hardware — pressure waves can interfere with electronics or stress fixation sites.
  • Active malignancy or tumor sites: Do not treat over or near any known or suspected tumor; shockwave-induced circulation increase can accelerate abnormal cell activity.
  • Open wounds, active infection, or inflamed skin: Applying the Kalecope Q60 or T800 handpiece directly over broken or infected skin introduces trauma to already-compromised tissue.
  • Bone growth plates in adolescents: Avoid treating near epiphyseal growth plates in patients who have not reached skeletal maturity — pressure waves can disrupt normal bone development.
  • Major nerve trunks and superficial arteries: Keep treatment heads away from the radial nerve at the elbow, femoral artery at the groin, and similar structures — direct application risks nerve irritation or vascular injury.
