Same message goes for massage therapy too. Some clients may feel instant relief but for many, especially those with chronic pain, it may take several sessions. Muscle tension and improper biomechanics/movement did not happen over night but rather over months, even years. Therefore, for a muscle/s to release, more than 1 session is likely needed along with retraining for proper posture and movement. As an LMT, my job is to facilitate healing.
