<s>[INST] Had a little vertigo about a month ago. Nothing major but I still have some dizziness if I look up or down. Now I feel like I have either a cold, flu or sinus infection. Went to a dr right after the vertigo and he checked my ears and sinuses which showed nothing. Is it possible that I got an infection now. [/INST] Hi Dear,Welcome to HCM.Understanding your concer. As per your query you have dizziness and sinus infection and vertigo. Well there can be many reasons for vertigo , but the most common is anxiety and the other Benign paroxysmal positional vertigo (BPPV) are ear infection , hypoglycemia , anemia , meniere's disease , migraine and alteration in he blood circulation . Ear infection sometimes occur when infection spread from post nasal drip , which further occur due to sinusitis . Infection spread to ear through eustachian tube . So it is possible that you get infection now . Dizziness is a symptom of vertigo . I would suggest you to consult ENT specialist for proper examination . Doctor may order certain test like CT scan for sinusitis  , MRI , blood test , audiometery test, and ECG to confirm the diagnosis.Doctor may prescribe antiemetic drug alon with antibiotics ( gentamicin ) and anti allergic . i would like to suggest you some home remedies drink green tea with ginger thrice a day and drink lots of fluids like juices and water . Avoid caffeine product and bending froward .Hope your concern has been resolved.Get Well Soon.Best Wishes,Dr. Harry Maheshwari </s>
