Unilateral pulsatile tinnitus


Hello Doctor: During my pregnancy this year, I occasionally experienced a pulsatile tinnitus in my left ear, which sounded like my heartbeat (not constant, just occasionally).
I thought it would resolve after giving birth, and now that it has been a month since delivery, I have hardly heard it again.
Recently, due to a confirmed diagnosis, I have been particularly fatigued, waking up at night to feed the baby, and experiencing sleep deprivation.
Last night, while feeding the baby, I turned my head to the right and suddenly noticed that when my neck was at a certain angle, I could hear the heartbeat in my left ear.
However, if I don't turn my head in that way, I can't hear it.
What could be the possible cause of this? I tried to make an appointment with you online, but all slots are currently full.
Given that I have to drop off and pick up my child, the earliest I can get an appointment is in about two weeks.
Would that be too late if this symptom requires immediate attention? Thank you.

Hello, if the tinnitus is not persistent pulsatile or accompanied by hearing loss, it is mostly benign tinnitus.
It may be related to the pulsation of blood vessels in the ear that can be transmitted to the ear in certain positions, so you may observe it on your own.
However, if you are concerned or if the symptoms persist without improvement, it is advisable to consult an otolaryngologist for examination.

More Info


Pulsatile tinnitus is a type of ear ringing that is often described as a rhythmic sound that coincides with the heartbeat. It can be a concerning symptom, especially for new mothers who are already dealing with the physical and emotional stresses of childbirth and caring for a newborn. In your case, the fact that you experienced this symptom during pregnancy and that it has persisted intermittently postpartum, particularly when you turn your head, is noteworthy.

There are several potential causes of pulsatile tinnitus. One common cause is vascular issues, where blood flow changes in the vessels near the ear can create a sound that is perceived as a heartbeat. This can occur due to increased blood flow during pregnancy, changes in blood pressure, or even anatomical variations in the blood vessels. Additionally, conditions such as hypertension or anemia can also contribute to this phenomenon.
Another possibility is that the sound you are hearing is related to changes in the middle ear or inner ear structures. For example, Eustachian tube dysfunction, which can occur during pregnancy due to hormonal changes, might lead to a sensation of fullness or pressure in the ear, which could be perceived as pulsatile tinnitus.
In your case, the fact that the sound is only noticeable when you turn your head suggests that it may be related to the positioning of blood vessels or even muscle tension in the neck that could be affecting blood flow or nerve pathways associated with hearing.
As for when to seek help, while pulsatile tinnitus can sometimes be benign, it is essential to consult a healthcare professional if the symptom persists, worsens, or is accompanied by other concerning symptoms such as hearing loss, dizziness, or headaches. Given that you are experiencing this symptom postpartum and have had a recent diagnosis that has left you feeling particularly fatigued, it would be prudent to discuss this with your doctor as soon as you can.
In the meantime, try to manage your stress levels and ensure you are getting adequate rest, as fatigue can exacerbate many symptoms, including tinnitus. If you find that the symptom is significantly affecting your quality of life or causing you anxiety, consider seeking an earlier appointment or discussing your concerns with a healthcare provider who may be able to offer advice or reassurance over the phone.

In summary, while pulsatile tinnitus can be benign, it is essential to monitor your symptoms and seek medical advice, especially given your recent postpartum status and the changes your body has undergone. Your health and well-being are paramount, and addressing any concerns early can help ensure that you receive the appropriate care and support.
