The sound of a drum in your ear when you tap your head could be a sign of pulsatile tinnitus.
Understanding Pulsatile Tinnitus
Pulsatile tinnitus is a type of tinnitus where you hear a rhythmic pulsing, throbbing, or drumming sound in your ear that often coincides with your heartbeat. It's unlike regular tinnitus, which is usually perceived as a constant ringing, buzzing, or hissing.
Possible Causes
While tapping your head might simply be amplifying a pre-existing sound, the "drumming" sensation can stem from several underlying causes related to blood flow or structural issues near the ear:
-
Vascular Issues: Abnormal blood flow in the arteries or veins near your ear can cause a pulsing sound. This might be due to:
- Arteriovenous malformations (AVMs): Abnormal connections between arteries and veins.
- Atherosclerosis: Hardening of the arteries.
- Tumors pressing on blood vessels: Growths that affect blood flow.
-
Middle Ear Problems: Issues in the middle ear can sometimes amplify internal sounds.
-
Muscle Spasms: Spasms in the muscles of the middle ear or around the ear can produce rhythmic clicking or thumping sounds.
What to Do
If you experience a persistent drumming sound in your ear, especially when tapping your head, it is essential to:
-
Consult a Doctor: See an otolaryngologist (ENT doctor) or your primary care physician.
-
Describe Your Symptoms: Be specific about the nature of the sound, its timing (constant or intermittent), and any other associated symptoms (dizziness, hearing loss, headache).
-
Undergo Diagnostic Tests: Your doctor may recommend tests like:
- Hearing test (audiogram): To assess your hearing.
- Imaging scans (MRI, CT scan): To visualize blood vessels and structures near the ear.
- Ultrasound: To evaluate blood flow.
In Summary
Hearing a drum-like sound when you tap your head is a reason to get checked by a doctor. While it could be a benign issue, it can also indicate pulsatile tinnitus, potentially related to vascular problems that need proper diagnosis and management. Don't self-diagnose and seek professional medical advice.
