Hi Alyssia..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain and presentation of symptoms it seems that you have maxillary
sinus infection known as Sinusitis and congestion,pain in teeth and nostril is due to it..
It is also possible that the infection in sinus can be secondary to
tooth infection specifically molar infection as the roots of upper molars many a times lie either very close to or at times within the sinus cavity..
You should
consult a dentist and get evaluated and in case of dental infection causing sinusitis a course of antibiotics and painkillers can be advised..
Tooth infection can be treated with either
root canal treatment or extraction and the sinus infection will be treated with antibiotics for atleast 15 days..
For
nasal congestion decongestant nasal sprays and oral medications can also be advised..
Hope this information helps..
Thanks and regards..
