Celtics draft pick Robert Williams has popliteal artery entrapment syndrome (PAES) in both of his legs, MassLive’s Fred Katz reported Monday night citing multiple sources.
PAES is a rare vascular disease in which the positioning of one’s muscles and tendons causes compression of the main artery that runs through the knee. It is most often found in male athletes under the age of 30. According to the Cleveland Clinic, patients with PAES typically suffer from “aching pain, numbness, and tiredness or cramping in the calf when they exercise,” but the symptoms are typically alleviated after three to five minutes of rest.
