Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
throat irritation along with cough and tightness of chest can be due to a number of causes like Upper
Respiratory Tract Infection, Bronchitis,
Lung infection, acid reflux, allergies etc..
I would suggest you to consult an Otolaryngologist or a Pulmonologist and get evaluated and he can also advice you investigations like throat swab culture, chest x Ray and also allergic test to rule out the exact cause of symptoms and treatment you accordingly..
You can be advised to take antibiotics like
Azithromycin, anti allergics like Allegra or Levocetrizine, decongestant like Pseudoephadrine, mucolytics like Ambroxol and cough expectorant containing Guaifenesin and
Dextromethorphan..
Warm saline gargles, steam inhalation and using a humidifier can help..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
