What causes headache, fever and swollen cheek post a tooth injury?
Patient: 2 weeks ago three of met top back teeth hurt. X-rays were clear but took 7 days of antibiotics.   After exam by dentist my cheek was swelled for 4 days. This past wed. I had severe headache neck pain and fever. Now sore throat. I'm on my 4th day of this. What could be happening? Doctor: Hi..Thanks for the query..If the x ray of teeth was clear and you still have pain in upper teeth along with cheek swelling, headache, neck pain and fever then it can be probably related to infection in your sinuses or Sinusitis..So my suggestion to you is to consult an Emergency room and get evaluated.A PNS View x ray of sinuses can be done to confirm the diagnosis..In case of sinus infection you can be advised another course of antibiotics for atleast a week along with anti inflammatory painkillers like Advil, decongestant nasal sprays and steam inhalation..For now you can take Advil to reduce pain and swelling..Hope this helps..Regards.
