7. Head or Neck Injuries
Trauma to your head or neck can damage your auditory nerves, inner ear structures, or the parts of your brain that process sound.
The science: Whiplash, concussions, and other head injuries can cause unilateral tinnitus (ringing in one ear). The risk is higher if the injury affected your hearing, caused dizziness, or resulted in a skull fracture.
What you can do: If tinnitus starts after a head injury, see a doctor immediately. You may need imaging (CT or MRI) to rule out serious damage.
8. Vascular Conditions (Pulsatile Tinnitus)
This is when your tinnitus sounds like a rhythmic whoosh—in time with your heartbeat. It’s called pulsatile tinnitus.
Possible causes:
High blood pressure
Atherosclerosis (hardened arteries)
Blood vessel malformations
Tumors near blood vessels
Anemia (low red blood cells)
What you can do: Pulsatile tinnitus is less common but more likely to have a treatable medical cause. See a doctor, especially if the sound is constant or bothersome.
9. Other Medical Conditions
Tinnitus has been linked to:
Anemia and iron deficiency
Thyroid disease (especially hypothyroidism)
Diabetes (high blood sugar can damage blood vessels and nerves)
Multiple sclerosis (can affect auditory nerve pathways)
Lyme disease
Acoustic neuroma (benign tumor on the auditory nerve—very rare but serious)
When Is Tinnitus Serious? (Red Flags to Watch For)
This is the most important section. Most tinnitus is annoying but harmless. However, certain symptoms mean you need to see a doctor—soon.
See a doctor immediately if tinnitus is accompanied by:
Sudden hearing loss (wake up unable to hear in one ear)
Dizziness or vertigo (room-spinning sensation)
Nausea or vomiting (especially with dizziness)
Weakness or numbness on one side of your face or body
Double vision or other vision changes
Severe headache (especially if new or different from your usual headaches)
Ear pain or drainage (signs of infection)
Tinnitus in only one ear (more concerning than both ears)
Pulsatile tinnitus (rhythmic whooshing)
Sudden hearing loss is an emergency. If you wake up with significant hearing loss in one ear, see a doctor within 24-48 hours. Early treatment with steroids can sometimes restore hearing. Delay reduces the chance of recovery.
What Will the Doctor Do? (What to Expect)
If you see a doctor for tinnitus, here’s what typically happens.
