Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that pain in nose along with pressure on right side of face and headache is most probably due to infection in the sinuses leading to 
Sinusitis I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation 
and investigations like PNS view x ray or MRI scan can help in diagnosis and treatment can be done 
accordingly..
You can be advised a course of antibiotics, anti-inflammatory painkiller like 
Ibuprofen, decongestants 
like Pseudoephadrine, do saline 
nasal irrigation, steam inhalation and use a humidifier in your room..
You can also be advised decongestant nasal sprays containing 
Xylometazoline or 
Oxymetazoline..
Avoid spicy and chilled foods..
Do warm compresses around nostrils.
Hope this information helps..
Thanks and regards.
