Hello,
thanks for using health care magic.
What you have is an inflammation of your pharynx in response to a stimulus.
Such stimulus could be viral, bacterial or allergic.
It would have been more helpful is you stated the day you did the culture. More so, one day for a culture doesn't really give a good result. However,
bacterial pharyngitis will present with fever and in this case fairly high.
Viral pharyngitis is very possible but should not be lasting more than a week or so. It does not present with considerable fever. However, later in its course, it could become super-infected by bacteria thus presenting with fever and worsening of symptoms.
Lastly but not the least,
allergic pharyngitis is possible especially in people with known allergies, or those with family history of allergies,
asthma,
atopic dermatitis etc. The characteristic worsening of symptoms in the morning if associated with
sneezing makes the diagnosis more likely to be of allergic origin. This will imply you are allergic to substances in your house: fungi, insect dust etc in which case you will need some antihistamines and
steroids for management.
However, it will be advisable to visit an ENT or your doctor for an indept evaluation and prescription.
Best regards and hope this helps.
