i am 22 and have had a cough and flue like symptoms for almost 2 months now. i went to the dr three weeks ago and had a blood test and chest x ray taken which botChatDoctore back normal. yester day when i had a follow up my dr said that the cough is most likly apshma related which i find questionable. i have aphsma but have not had serious problems for years and have not noticed any wheasing. the dr told me that they did hear wheasing and i believ them but apshma does not explain the head ache and muscle pain and fatigue. im willing to trust the dr and take the new alirgy med she perscribed in the hopes that this will all go away but was simply wondering about other possibilities

### output:

Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, you are mostly having post infectious bronchitis. Bronchitis is inflammation of airways and this is common after viral upper respiratory tract infection (URI) like flu. Bronchitis can cause cough, wheezing, headache, fatigue, muscle pain etc. So consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (pulmonary function test). PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilator (formoterol or albuterol) and inhaled corticosteroids (ICS) (budesonide or fluticasone).Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
