Most people feel an instant release of tension after their initial treatments. However in some cases due to the body being overstimulated and not used to the treatment you may feel sore the day after. It is also due the fact that we are applying “corrections” to the mechanics and function of the body and the body has to adapt to this. However this should subside over the coming days and reduce with further treatments as your condition improves. You can liken this to when you start a gym program and your muscles are shocked by the initial stress you put them under and pull up sore the next day.
