Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of severe cough along with stinging in chest and
sinus infection can be due to causes like Chronic upper
respiratory tract infection, bronchitis, lung infection, Chronic
Obstructive Pulmonary Disease etc..
I would suggest you to
consult a Pulmonologist and get evaluated and he can do a clinical evaluation and also advise you
sputum culture, PNS View x Ray of sinuses and chest x ray to rule out the exact cause of the symptoms and treat accordingly..
He can advise you to take antibiotics, anti inflammatory painkiller, mucolytics, cough suppressant, anti allergics, steam inhalation and warm saline gargles..
Avoid spicy, chilled and citrus foods..
Sip on warm water throughout the day.
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
