I’ve had bad muscle spasms for 19 years. I found deep tissue massages helped a lot with the right massage therapist but they get very expensive. I tried out a number of different massage tools and found the percussion massage gun was like getting a professional massage and it can maneuver to reach any part of the body.
I also used Formula 303 for 14 years to treat muscle spasms when they got so bad I couldn’t work and as a sleep aid. I don’t use it as much now since purchasing the percussion massage gun.
Not medical advice.
