I get why you’re confused — this started like an ear problem, not a brain one. Foul-smelling discharge, ear pain, ringing + vertigo strongly point to an inner/middle ear (vestibular) cause. The MRI being normal supports that. The recent return of vertigo and vomiting usually means the ear issue hasn’t fully settled, not that something new has started.
At this stage, ENT is the right primary doctor, preferably one who deals with vertigo/inner ear disorders. Neurology is useful only if there are red flags (weakness, speech issues, persistent double vision), which you haven’t mentioned.
Next Steps
• Detailed ear exam + hearing test (audiometry)
• Check for ongoing infection or inner ear inflammation
• Vertigo-specific management (sometimes repositioning maneuvers + targeted meds work better than long courses of Vertin alone)
Health Tips
Vertigo often needs fine-tuning, not just medicines. If you want, we can go step-by-step (symptom pattern, triggers, meds you took, MRI report) and narrow this down properly so you know exactly why it’s recurring and how to stop it.
