Most experts recommend using a massage gun on a spot for at least 15 seconds but no more than 2 minutes. Quick treatments of 15 to 30 seconds work best to activate or reactivate muscles, while longer treatments of up to 2 minutes can help with pain relief and muscle recovery.;It’s usually unnecessary to use a massage gun daily, but you can if you find you’re getting better results. As with any treatment, if the massage gun is causing pain instead of reducing it, discontinue use and consult your doctor.;
