I used to massage an older man who had really hard muscle tissue. I massaged this tissue and now it is pliable soft tissue :)
Just recently I had a man who drives a lot and his shoulder used to play up, stop him from sleeping, hurt and more. It took a couple of appointments to work out where the issue was originating from however we still managed to decrease the level of pain, improve the quality of sleep and for about three days he had no pain. Now, he gets full body massages once a month to maintain his health.
Happy customer = Happy therapist
