### input:
I have been sick for over a week now.  It started with a horrible sore throat where I sent to the Dr. who prescribed Loratidine and a Z-pack.  This is the exact same thing he prescribed to me back in May that didnt seem to work then.  I was sick for over a month!  Now I feel exactly like I did then.  Sure my throat doesnt hurt anymore but I feel like it has just settled in my chest.  I have a runny nose and a nagging cough that yes, sometimes is productive.  Last time I called and told him I wasnt better he just gave me a prescription cough medicine - which I still have so I used it last night but this doesnt solve my problem.  My voice sounds terrible and my chest hurts.  And the coughing is annoying.  HELP!

### output:

Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should definitely rule out lung infection (pneumonia) and bronchitis in your case because you are having recurrent symptoms of constant productive cough and chest pain. So better to consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT (Pulmonary Function Test). Chest x-ray is needed to rule out lung infection. PFT is must for the diagnosis of bronchitis. You may need higher antibiotics, inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone) based on the reports.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.
