Hi,
Noted your history well and understood the concerns.
Nose blockage can not cause pain on side of body as you have mentioned for. The cause can be in the
cervical spine or brain and needs MRI of the spine and brain after Neurological evaluation.
Sine nose block has continued even after treatment means you need to get
CT scan of the nose and
sinuses as this will define the cause perfectly and give way to the management.
Mild cases need 3 weeks course of medicines as per the cause found.
If the sinuses are full or there is deviated
nasal septum causing the blockage then only a corrective surgery is needed.
Consult an ENT Surgeon for clinical evaluation, examination, Nasal
Endoscopy and get a proper diagnosis and management.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT & General Surgeon
