Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain it seems like there have been few small fragments of broken bone chips into the sinus cavity as well as there is infection in sinus causing
Sinusitis which is responsible for the symptoms of headache and pressure over the face that you are experiencing..
You should consult an Otolaryngologist and get evaluated and he/she can also advise you to get a PNS view
x ray done as well as
MRI SCAN if required to rule out the exact condition of the sinus and treat you accordingly..
As of now for symptomatic relief you can take a course of antibiotics like
Augmentin and take anti-inflammatory painkiller like
Ibuprofen to reduce pain and inflammation.
Do steam inhalations, use saline nasal sprays,and use a humidifier in your room.
Do not delay consulting the physician as it can further increase the infection and complications..
Hope this information helps..
Thanks and regards.
