Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that along with cold you have also got
sinus infection leading to sinus pressure..
You should continue taking
Mucinex D as it contains cough expectorant
Guaifenesin and decongestant
Phenylephrine..
You can also take mucolytics like Ambroxol, anti allergics like Levocetrizine and anti inflammatory painkiller like Ibuprofen..
You can do saline
nasal irrigation and steam inhalation..
Use a cool mist humidifier in your room as it will help in easing breathing..
You can also chew a Vitamin C pellet to boost immunity..
Avoid spicy and chilled foods..
Drink plenty of warm water..
Do warm compresses around the nose to relieve pressure..
Hope this information helps..
Thanks and regards.
