If you suspect that a wasp sting is infected, it is important to seek medical attention promptly. An increase in swelling, hardness, heat, and pain around the sting site can be signs of infection and should not be ignored. You can try applying ice to the area for 15 minutes at a time to reduce inflammation while waiting to see a doctor. It is recommended to seek medical care promptly to avoid any delays in receiving the appropriate treatment. You can check for walk-in clinics in your area or try scheduling an appointment online through platforms such as Rendez-vous Santé Québec or Bonjour Santé. Teleconsultation services like Dialogue could also be considered for a consultation, albeit with associated fees.
