What causes you to hear your blood pulsing in your ears?

Hearing your blood pulsing in your ears, often referred to as pulsatile tinnitus, can be caused by various factors, including increased blood flow in the vessels near the ears, changes in blood pressure, or conditions affecting the ear's structures. It may also occur due to heightened awareness of internal sounds or issues like earwax buildup or ear infections. Stress and anxiety can exacerbate the perception of this sound. If it is persistent or bothersome, consulting a healthcare professional is advisable.
