Girls, I'm in agony, I don't know what to do anymore. We went for an appointment and they diagnosed tonsillitis and conjunctivitis, prescribed treatment. The temperature keeps rising above 39. I gargle with antiseptic solution, but the temperature is still high. I called an ambulance, but couldn't bring it down. They gave me an injection saying it was tonsillitis. It rises again at night and during the day, the temperature goes above 39. It's normal during the day and around 37, maybe even lower. I can't handle this anymore, I'm exhausted. Could it be conjunctivitis that causes such a high temperature today
