Son had severe sore throat and headache 9 days ago. First went to get tested for Covid as per public health guidelines. Covid test negative. Signed up for Maple, paid $50. Diagnosis = cold. 5 days later still severe sore throat, bleeding uvula, swollen tonsils, pus pocket at back of throat. Went to walk-in clinic. Sent away due to Covid symptoms. Back on Maple. Described symptoms. Reply from Maple = cannot see you with those symptoms - no further f/u, no explanation, no nothing. He can t see a doctor in person, he can t see a doctor online. I m thinking these are not symptoms that should scare a doctor away... ??? And they are not symptoms to go to a hospital for. Kinda stuck here... :(
