A gua sha application may take several minutes or longer. After the gua sha treatment is completed, it is advised to take it easy for the rest of the day, including no alcohol.1 This recommendation to relax is based on the belief that the gua sha treatment has gotten the blood and energy flowing again, and too much activity too soon may reduce its benefits.
Sometimes gua sha is combined with other treatment methods, such as acupuncture.
Gua sha may look strange or appear painful to observers who are unfamiliar with this treatment. When a practitioner press-strokes the skin with a rounded edge during gua sha, the tiny blood vessels (capillaries) beneath the skin can break. This process makes the skin develop red spots (petechiae) and looks like a rash or bruise. The size and darkness of the resulting spots can vary greatly, depending on the patient’s condition as well as the practitioner’s skill. The redness usually goes away within 2 to 4 days.
Gua sha is not typically described as painful, but in some cases the application can be uncomfortable. The practitioner must feel (palpate) the neck for muscle tightness and other abnormalities, and the press-strokes applied during gua sha involve a significant amount of pressure (but not as much force as deep tissue massage).
In some cases, pain relief may begin immediately after the treatment is done. Although, not everyone experiences pain relief from gua sha.
