The adverse effects of gua sha may include skin redness or pain, and in some cases, may trigger rashes or papules. Severe reactions can even lead to skin disorders. Performing gua sha during pregnancy may increase the risk of threatened miscarriage. Gua sha is a relatively common physical therapy that helps improve blood circulation and expel cold from the body.
