Deep tissue massage is a type of therapeutic massage that focuses on realigning deeper layers of muscles and connective tissues. It is particularly beneficial for people with chronic aches and pains - such as stiff neck, upper back, low back pain, leg muscle tightness, or sore shoulders.On the other hand, a relaxation massage is often what comes to mind when most people think about massages. It is a gentle, soothing massage that promotes relaxation and stress relief without any focus on relieving muscle stiffness or improving mobility.
