Introduction
Sha (petechiae) appearing on the buttocks is due to blockage in the Yang Qiao Meridian. Many office workers today sit for long periods in front of computers with little physical activity. The prolonged contact between the thighs and the chair, particularly at the area where the Yang Qiao Meridian runs tangentially, easily leads to stagnation of qi and blood. This is why sha appears when scraping is performed. Since there is relatively less muscle in the buttocks, individuals who sit for extended periods may benefit from gua sha on the buttocks, and should also engage in appropriate exercise regularly to avoid prolonged sitting.
Sha (a dark red rash appearing during gua sha) on the buttocks occurs due to blockage in the Yang Qiao Meridian. Many office workers sit for long periods in front of computers, engage in little physical activity, and maintain prolonged contact between their thighs and chairs. Since the Yang Qiao Meridian runs along a tangential position where pressure is easily applied, qi and blood circulation in this meridian can become stagnant, leading to sha when performing gua sha. The muscles in the buttocks are relatively thin, so people who sit for extended periods may benefit from gua sha on the buttocks, while also incorporating appropriate physical activity into their daily routine to avoid prolonged sitting. Specific details are as follows:
From a biomechanical perspective of sitting posture, the Yang Qiao Meridian bears significant pressure. The Qiao Meridians ascend from the inner and outer sides of the lower limbs to the head and face, responsible for connecting the body's yin and yang energies and regulating muscle movement, particularly enabling agile and swift motion of the lower limbs. Both Yin and Yang Qiao Meridians converge at the inner corner of the eye, indicating their role in nourishing the eyes and controlling eyelid opening and closing. Many computer users experience eye pain, which is often related to blockages in the Yin and Yang Qiao Meridians.
If the sha is mild, no special treatment is needed—it typically resolves spontaneously within two to three days. If the sha is severe, appearing deep purple or blackish-purple, stop gua sha or massage on the buttocks immediately. Apply a warm towel compress to the affected area; symptoms usually subside within five to seven days.
