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 got a viral infection leading to loss of voice known as
Laryngitis along with coughing mucous..
I would suggest you to consult an Otolaryngologist and get evaluated and a he can do a
laryngoscopy and
sputum culture to rule out the exact cause of problem and treat you accordingly..
You can be advised to take a course of antibiotics like
Augmentin or
Azithromycin, anti-inflammatory painkiller like Ibuprofen, mucolytics like Ambroxol, anti allergics like Benadryl..
Do warm saline gargles, steam inhalations and use a humidifier in your room..
You can also sip on warm water throughout the day as it will help in relieving throat and improve voice..
Suck throat lozenges and chew vitamin C pellets..
Do not strain your vocal cords by trying to speak with applying force..
Hope this information helps..
Thanks and regards.
