Detailed Answer:
Hello and welcome to Ask A Doctor service.

I have reviewed your query and here is my advice.

Your information is inadequate to come to a diagnosis. Can you send more details about your symptoms?

In the meantime you should consult an Ent surgeon and get a nasal endoscopy and x ray sinus done. Any nose pathology specially allergic rhinitis can cause headache. So you need to consult an Ent surgeon. If needed you may need to take fluticasone nasal spray, steam inhalation to relieve the sinusitis. Fir rotating sensation you mat need to consult an Ent surgeon and a physician.

As there are many causes for giddiness you need to get thoroughly checked specially for your blood pressure, cardiac and neurological conditions. Accordingly treatment will continue.

Please review if you have any queries.
