Is Laser Therapy Harmful? Side Effects and Risks
When it comes to laser therapy, there are a lot of misconceptions about the potential risks and side effects. In this blog post, we will discuss the potential benefits of laser therapy, along with its risks and precautions.
There’s a lot of interest in laser therapy, including its possible effects on pain and inflammation, but the evidence for it is mixed.
But like any other medical procedure, laser therapy does come with some risks. This blog post will take a closer look at both positive effects and potential precautions. We’ll also discuss its possible benefits and how to weigh the pros and cons to make an informed decision about whether this treatment is right for you.
Is Laser Therapy Harmful?
Laser therapy is generally well tolerated when delivered by a trained professional, but it does carry some risks, particularly to the eyes, and it isn’t suitable for everyone (see below).
Laser therapy has been used to treat various conditions, including pain, inflammation, and wound healing. While it is generally considered safe, some potential risks are associated with laser therapy.
Risks & Contraindications For Laser Therapy
Cold laser therapy, for example, should not be used on carcinomas or cancerous lesions. In addition, patients with pacemakers or other implanted medical devices should avoid laser therapy as the light energy can interfere with the functioning of these devices.
According to The North American Association for Laser Therapy conference held in 2010, the following contraindications and cautions were indicated:
- Never aim the beam at the eyes; always wear protective eyewear as the laser can cause significant damage to the eyes.
- Do not treat an area of “known primary carcinoma or secondary metastasis unless the patient is undergoing chemotherapy; when LLLT can be used to reduce side effects such as mucositis.”
- Laser therapy is not recommended to be used directly over a growing baby during pregnancy.
- Pulsed laser therapy is not recommended for those with photosensitive epilepsy as the visible light may cause a seizure. [1]
As with any medical treatment, you must speak with your doctor or qualified healthcare provider before undergoing laser therapy to ensure it is safe.
What Laser Therapy Involves
Laser therapy uses focused light applied to the skin over the painful area. Some of the light is absorbed by light-sensitive molecules in the tissue called “chromophores.” Laboratory studies have proposed effects on pain and inflammation, but how much these matter for patients is not well established.
Laser therapy is used for various musculoskeletal conditions, including:
What Does The Evidence Show?
The evidence for laser therapy is mixed. Some studies report less pain for some conditions and others show little benefit, and results vary from person to person.
How Often Would I Need Laser Therapy?
The number and length of sessions depend on the area being treated and how you respond. Your plan is set after assessment. The literature does not state any specific optimal dosage because there are many variables to consider when prescribing laser therapy.
According to a study published by the Clinical Sciences Department, Texas Chiropractic College [2], the variables that determine the recommended dosage are:
- The power output of the laser.
- The size of the area you are working on and the thickness of the tissue.
- If the laser is continuous or pulsed.
- The time of application.
- The kind of laser.
Is There Downtime After A Laser Session?
There is no downtime after laser therapy, although sometimes it is best to rest – we will talk about this a little later.
However, we recommend avoiding intense, strenuous exercise if you receive laser therapy for a present injury. Your laser therapy session could reduce your pain, making you more likely to push yourself a little too hard.
What Can I Expect After My First Session Of Laser Therapy?
Some people notice a small change after a first session, such as feeling slightly looser; others notice no change. Results vary.
Should I Rest After Laser Therapy?
It is also typical to temporarily feel a slight increase in symptoms after your first session. It is also not uncommon for clients to feel tired; we recommend listening to this intuitively and resting.
Does It Cause Pain?
Most people find laser therapy comfortable and feel a mild warmth. Tell us if it feels too warm and we’ll adjust.
Conclusion
Laser therapy is generally well tolerated when delivered by a trained professional, but it isn’t suitable for everyone. Finding a laser therapy provider you trust and who has experience is essential.
