Hello and hope you are doing well.
It could be sinusitis, if it is accompanied by nasal stuffiness and facial pain or pressure. Sinus infections can cause stuffiness of the nose with nasal blockage, which can make breathing through the nose difficult. It can also cause post nasal drip and lead to an irritation in the throat. You will need to consult your primary care physician for proper assessment. In the meantime practice good breathing exercises, humidify your room and do steam inhalations.
Hope this helped and do keep us posted.
