Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that due to cold there has been infection in ear as well as.pain in cheek and headache seems to be due to
Sinus infection or Sinusitis while jaw pain can be
radiating pain from ear..
I would suggest you to consult with an Otolaryngologist and get evaluated and an Otoscopic examination, PNS view or MRI of sinuses can help in diagnosis and treatment can be done accordingly..
You can be advised to take a course of antibiotics, anti inflammatory painkiller like Ibuprofen, decongestant like
Phenylephrine, anti allergics like Benadryl or Allegra, antibiotic and
analgesic ear drops..
Saline
nasal irrigation and steam inhalation can help.
Avoid chilled foods and air-conditioning atmosphere..
Avoid excessive water exposure to ears..
Hope this information helps..
Thanks and regards.
