Hi thanks for contacting HCM. Noted you have cough , runny nose with voice also affected. So here you could have viral flu or viral infection of respiratory tract... There are also chance of viral laryngitis as voice affected... So you can consult ENT surgeon for laryngoscopic examination... Here symptomatic management done with decongestent use... Steam inhalation also useful. Humidifier can be used. If no improvement then short term steroid can be used.... Azelestine nasal spray also useful.... Drink more water ... Fruit juices taken more.... Avoid excess spicy food.... If no improvement and condition worsening then chest x ray done for further work up. Hope your concern solved. Take care. Dr.Parth Goswami
