Thanks for writing your query.
I hope the X-Ray you have mentioned is the X-Ray PNS.
Your symptoms are suggestive of nasal congestion
. You should get yourself examined by an ENT specialist
to investigate the cause of one sided nasal blockage-whether it is by mucus or by some growth of the nasal tissue.
Also get a culture/senstivity done of your nasal discharge.
Steam inhalation will be helpful in clearing the mucus from the nasal passage.
Antihistamininc like Cetrizine
along with a decongestant like Phenylepherine will be helpful in decreasing your symptoms.
for mild pain or Ibuprofen for severe pain
along with an antacid can be taken for relief from pain.
Antibiotic if needed, can be added according to the reports of the investigation.
Any medicine to be taken under medical supervision only.
I hope this is helpful to you.
