Q&A: I had bronchitis and four months later, I'm still sick. Do I have walking pneumonia?
Sounds like you have been sick for quite a while. I agree that you should see a regular Family Physician, rather than going to walk-in clinics, to get better comprehensive care. You could have just recurrent infections or a prolonged resistant one. I think as long as you aren't experiencing high fevers, chest pain, or difficulty breathing, you should be OK waiting until your scheduled appointment. If any of those symptoms occur, then you should go to the ER for more urgent treatment.
