Practitioner Al Sheikh Mohamed El-Sayed removes a cup from a patient as congealed blood is seen on the patient's back during a blood cupping session, or Hijama cupping therapy, inside a treatment room at a medical center in Shubra El-Kheima on the outskirts of Cairo, Egypt, August 13, 2016. Hijama or cupping therapy, an ancient treatment that uses glass cups and suction to help circulate blood and relieve muscle tension, was put into the spotlight during the Olympics after prominent athletes like U.S swimmer Michael Phelps hit the pool in Rio with circular red marks on his back.
