Hi Dear ,
Welcome to HCM,
Understanding your concern .As per your query you have phantom smell, pressure behind nose and headache. Well there can be many reasons for headache and dizziness like low blood glucose or iron level , benign paroxysmal positional vertigo (BPPV) , infection , meniere's disease , migraine , neurological ,
inner ear infection and due to certain medicines such as blood pressure medicines or anti depressants . It seems to me that in your case there is probably
sinusitis causing symptoms . I would suggest you to
consult ENT specialist for proper examination and rule out above causes . Doctor may order balancing test , rotatory chain test , hearing test ,
posturography and CT scan . Doctor may prescribe anti emetic drug , sedatives and alter the dose of BP medicines or prescribe some substitute . For now avoid bending forward and take ibuprofen or
acetaminophen for headache . Doctor may also refer you to cardiologist in case of cardiac problem .taking steam will help alot .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
