Hello. Thank you for asking at HCM. I went through your son s history. From your history, I would suspect allergies first rather than repeated mycoplasma pneumonia infections. I would like to ask a few questions: At what age did his asthma symptoms started? Does he have symptoms only during spring or other part of year also? Is he on any regular medications? Does his symptoms start with fever or without fever? How, in every spring, mycoplasma pneumonia was diagnosed? Does he have allergic rhinitis? Does any of his family members have allergies/asthma? However, from your history, personally I would like to investigate him for allergies to air-borne allergens. Depending upon the reports of the allergy testing, he may be advised avoidance measures and allergen specific immunotherapy if indicated. So my personal opinion to you is to consult an Allergist-Immunologist for identification and management of his allergies. However, if he is really having repeated mycoplasma pneumonias, you should be really concerned about it as it is uncommon in children with good immune system. Hope this will be helpful to you. Wish your son the best of the health. Should you have any further query, please feel free to ask at HCM. Regards.
