Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of
sore throat along with teeth aches that is not confined to a single tooth and headache when changing position can be most probably be due to inflammation of the sinuses causing
Sinusitis..
I would suggest you to consult an Otolaryngologist and get evaluated and he can also advise you PNS view or MRI SCAN of sinuses to confirm the cause so that treatment can be planned accordingly..
He can advise you antibiotics, anti inflammatory painkiller, steam inhalation, saline
nasal irrigation, Oral and nasal decongestant and steroid
nasal spray..
As of now you can do steam inhalation, saline nasal irrigation and take
Ibuprofen to reduce pain and inflammation..
Hope this information helps..
Thanks and regards.
