Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns.
As per your complain it seems that you are suffering from Maxillary as well as
Frontal Sinusitis and leading to sinus pains and headache..
Sore throat seems to be due to
post nasal drip causing infection in throat.
I would suggest you to consult an Otolaryngologist and get evaluated and he can advise you a PNS View x ray or MRI of sinuses to confirm the cause..
For sinusitis he can advise you to take a course of antibiotics like
Augmentin, anti-inflammatory painkiller like Ibuprofen, decongestants like
Phenylephrine,anti allergics like Allegra,steam inhalations, saline nasal irrigations and decongestant nasal sprays..
While sleeping sleep with head slightly raised and chin down to ease the drainage and prevent congestion..
Avoid air conditions environment to prevent congestion..
For sore throat do warm saline gargles and suck throat lozenges..
Chew a Vitamin C pellet daily..
Hope this information helps..
Thanks and regards.
