I'm sorry to hear you're experiencing pain and swelling near your ear along with dizziness and difficulty standing. These symptoms could indicate an ear infection, inflammation, or possibly an inner ear problem affecting your balance. Since you also have a history of migraines, it’s important to differentiate whether these symptoms are related or separate issues.

Here are some important points and steps you should consider:

• Pain and swelling near the ear may suggest an infection such as otitis externa (outer ear infection) or otitis media (middle ear infection), or possibly inflammation of nearby glands.
• Dizziness and difficulty standing could be related to inner ear problems affecting balance, such as vestibular neuritis or labyrinthitis, or could be linked to migraine-associated vertigo.
• Because these symptoms can sometimes indicate serious conditions, it is important to seek prompt evaluation.
• Avoid sudden head movements and rest in a safe place to prevent falls.
• If you have fever, worsening pain, hearing loss, or neurological symptoms (like weakness or severe headache), seek emergency care immediately.

Recommendation: Please consult an Ear, Nose, and Throat (ENT) specialist as soon as possible for a thorough examination and appropriate treatment. If your dizziness or balance issues worsen or you feel faint, consider visiting an emergency department promptly.

If you have migraine history, also inform your neurologist about these new symptoms to rule out migraine complications.
