ear pain followed by vertigo, vomiting, ringing in the ear, and now persistent headache with eye/temple pain — this sounds like it could be related to an inner ear problem (like vestibular neuritis or labyrinthitis) or sometimes migraine associated with vertigo.
The good news is that your BP,
sugar, ECG, and blood tests are normal, so serious heart or acute stroke-related causes are less likely.
I would advice:
Vertin (betahistine) is commonly given for vertigo and imbalance.
Naxdom is a migraine pain reliever, but if your headache is still severe and constant, you should follow up again.
Eye pain and temple pain can sometimes point toward migraine or sinus-related issues.
Next Steps
If the headache is severe, one-sided, with nausea, or not improving with medicines, see a neurologist or ENT specialist.
If vertigo or imbalance gets worse, or you develop double vision, weakness in limbs, slurred speech, or severe vomiting, go to the hospital immediately to rule out any neurological cause.
Health Tips
In the meantime: rest in a quiet room, avoid sudden head movements, keep hydrated, and continue the medicines as prescribed.
