What is an adverse effect of laser therapy that may occur temporarily?

In the context of laser therapy, increased pain during application is considered a temporary adverse effect that may occur due to various factors, such as sensitivity to the laser frequency, pre-existing conditions in the patient, or the type of tissue being treated. This phenomenon can happen as the laser interacts with the tissues, potentially eliciting an initial discomfort or exacerbation of symptoms before any therapeutic benefits are realized.

This is different from more severe adverse effects like severe allergic reactions, which are less common and typically related to medications or materials rather than the laser itself. Permanent skin damage is a serious and often avoidable outcome that should not occur with proper technique and settings, while long-term fatigue may result from broader health issues rather than being a typical direct consequence of laser therapy. Therefore, understanding that temporary discomfort is a possible transient response to treatment allows clinicians to manage patient expectations and address concerns promptly.
