What is a common side effect of ultrasound therapy?

Ultrasound therapy is a widely used treatment method that utilizes sound waves to promote healing and reduce pain. A common side effect of this therapy is temporary redness or warmth in the area being treated. This occurs because ultrasound generates heat through the vibrations of sound waves, which can increase blood flow to the targeted tissues. The resulting warmth and slight reddening are generally mild and indicate that circulation is being enhanced, which is beneficial for the healing process.

In contrast to other options, which are not typically associated with ultrasound therapy, temporary redness or warmth is a normal physiological response to the treatment. Patients often experience these sensations immediately after or during the ultrasound application, making it a well-recognized effect of this therapeutic modality. Understanding this can help patients manage their expectations and recognize that such sensations can indicate the therapy is working effectively.
