Have Medical Questions? Ask a Doctor Online!
Thank you for the question.
How many times have you had such episodes of sickness in the last year? What investigations were done? What treatment was prescribed by your doctor?
I definitely recommend further investigations. You should get a chest x-ray, sputum culture, and blood counts done. With the symptom of fever and wet cough, a bacterial infection is a possibility. Not treating it with an antibiotic will lead to recurrent infections. With treatment, you will avoid persistent infection. I don't think that there is any problem with your immune system.
