Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that you have an Upper
Respiratory tract infection leading to loss of voice or
Laryngitis and runny nose, coughing and headache..
I would suggest you to start taking antibiotics like
Azithromycin, anti-inflammatory painkiller like Ibuprofen, decongestants like Pseudoephadrine, mucolytics like Ambroxol, do warm saline gargles, steam inhalations and use a humidifier in your room..
Take cough suppressants containing Dexamethorphan and
guaifenesin..
Suck throat lozenges and chew a Vitamin C pellet daily..
In case of no improvement in a week
consult a Pulmonologist and get evaluated..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora..
