This can be a common experience for some people after a massage that didn’t feel particularly strong at the time. It occurs after an initial massage and is indicative of tension release and increased blood flow through the muscle tissue. This soreness will dissipate over the course of the day. If pain was the subject of the treatment this will also dissipate as well. Taking a warm to hot bath at night on the day of the massage just before bed can improve the massage releasing effects.
