Massage guns are very useful tools to help relax muscles and reduce pain, but they can cause serious injuries if used incorrectly. In this article, we ignore the sales talk and look at the research on massage guns to explain how you can use them safely for best effect. Remember, if you need more help with an injury, you're welcome to consult one of our physios online via video call.

Benefits of using a massage gun
In my experience, using a massage gun is the most effective way to give yourself a massage, and the research does seem to support their use.
It’s important to note that the current research on massage guns is a bit patchy, and there’s a lack of high-quality studies. So, the current research results should not be seen as 100% accurate – some of it may still be proven wrong by more thorough research.
Massage gun benefits supported by research include:
Decreasing pain: The research seems to suggest that massage guns are better than placebo, foam rolling, and sports massage at decreasing pain.
Improving flexibility: The available research seems to agree that massage guns can improve flexibility.
Increasing performance (strength and explosive strength): The available research is of very low quality and shows contradictory results for this.
Helping recovery: The evidence suggests that massage guns can improve short-term recovery (between bouts of exercise spaced a few minutes apart), but the evidence for improving long-term recovery (how you perform the next day) is contradictory.
Massage guns can cause severe damage
Massage guns can cause serious injuries if you use them excessively or over sensitive areas. These are some of the dangerous side effects you want to avoid:
Damage to blood vessels (arteries and veins). There have been reports of people suffering strokes through damage to the arteries in their neck or blood clots that formed in other blood vessels. You can avoid this if you stick to using the massage gun over large muscles and avoid areas where blood vessels are prominent (see below).
Excessive damage to muscles leading to rhabdomyolysis (a condition that can damage the kidneys) either through excessive use or because the person has a systemic illness. This can be avoided by following the guidelines below.
Damage to eyes after using the gun on the face.
Damage to the pleura (the sack that surrounds the lungs).
General contraindications – When and where not to use a massage gun
Do not use a massage gun:
If you have a chronic condition like diabetes, iron deficiency, kidney disease, blood clotting disease, or any other condition that may make it easier to damage your cells
Over wounds, rashes, or blisters
Over areas with active inflammation
Over torn muscles, ligaments, or tendons
Over new scars (less than 12 weeks old)
Over fractures or areas of low bone density (osteoporosis)
On your face or head
On your neck
Over your chest (front or back) if you have any lung conditions, including asthma and emphysema
Over exposed arteries and veins, including near the collar bones, the armpits, crook of the elbow, front groin, back of the knee
In areas with little muscle (just skin and bone), including around the knee, ankle, or elbows, and on the hands or top of the feet
In areas where you don’t have normal sensation and can’t feel what is happening.
How to use a massage gun safely on yourself
Where to use a massage gun
You can use a massage gun over large muscles, for example the calves, hamstrings, quadriceps, back muscles, biceps, triceps, and muscles in the forearms. Check the contraindications above for what areas to avoid.
Massage gun settings and duration
These depend on your goals:
For recovery proposes it is currently recommended to use low frequencies (2 400 percussions per minute or lower) for 2 to 5 minutes per muscle group.
To improve flexibility the research suggests short duration treatments (maximum of 2 minutes per muscle group) at a high frequency (more than 2 400 percussions per minute).
It is not recommended that you use a massage gun shortly (less than 5 min) before a strength activity (especially an explosive one) because it may harm your performance.
But also use your common sense. For instance, if you have very large muscles, you may benefit from the upper treatment limits mentioned above. However, if you are a smaller person and don't have very large muscles, it is likely best to start with the lower limits.
How hard to press
Apply it at a “comfortably uncomfortable” intensity (about 4 to 6 out of 10 on a pain scale).
How often to use a massage gun
Leave at least 48 hours between treatments. Your body needs time to recover after a massage gun session.
