Thanks for posting you query to health care magic.
It is clearly indicate infection with some microorganism it could be Viral or Bacterial . As Upper
respiratory tract infection are commonly caused by viruses and secondarily infected with bacteria so dual infection may be there and it involved your neck gland also
.So first you should be investigated for :
1.
complete blood count to see level of infection.
2.
X Ray Paranasal sinuses to find out which sinus is involve and level of involvement.
presently you can take:
1 tablet Aceclophenac 100 mg orally after meal two times a day for relieving headache.
2. Syrup containing AMbroxole with Ctrizine three times a day for cough.
3.
Oxymetazoline 0.05% nasal drop two times a day for nose block
review me after investigation report then I will suggest you complete treatment.
medication should be taken under supervision of clinician.
Hope you would be satisfied with my answer . Feel free to communicate if any query .
