Hi Dear ,
As per your query your friend has
sudden dizziness, nausea and
lightheadedness 20 - 30 minutes ago . Well there can be many reasons for dizziness like ,
Low blood sugar and iron level , Some medications like anti-seizure drugs, antidepressants, sedatives and tranquilizers , Ear infection , Due to sonme medication , Benign paroxysmal positional vertigo , Meniere's disease and Migraine . As it happen 20-30 minutes ago it must not be due to some serious problem . I would suggest you to
consult ENT specialist for proper examination . Doctor may order certain tests like CT scan , blood test , rotatory chair test , posturography and examination with otoscope . Doctor may prescribe antiemetic drug , antibiotics (amoxicillin or penicillin ) at least for 10 days , antihistamine ,
Prochlorperazine and recommend vestibular therapy . For now do warm saline gargles and take stean twice daily .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
