I have had knots in my shoulders, back and calves for over 20 years. I saw a massage therapist that did deep tissue massages and he was a ex nurse. He could never get rid of my knots. The neurologist did an EMG on me and diagnosed me with severe dystonia. The neurologist Botox’s the muscles and they some what relax but they don’t go away. I just live with it. Some times they contract so much the neurologist does cortisone injections and my neck will pop into place.
Bottom line there is nothing that works.
Ask the doctor about Botox. Medications for muscle spasms do nothing.
