Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that nasal congestion
along with pressure and headache and numbness under the eye and congestion in nose are all pointing towards Sinus infection
as major sinuses are present in the area adjacent to nose and back of eye..
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
Avoid spicy and chilled foods..
Do warm compresses around nostrils..
Hope this information helps..
Thanks and regards.
