I recently did some exercise for about half an hour, and afterward, I felt my heartbeat kind of radiating up to my head, which was really unusual. I could actually hear my heartbeat and felt this throbbing in my head. I did an ECG and echo2D a couple of weeks ago, and everything seemed okay back then. Is this something I should be worried about or should I go see a doctor?

It is not uncommon to experience a sensation of your heartbeat in your head after exercise, especially if you have been exerting yourself. This is known as pulsatile tinnitus and can be a normal response to physical activity. However, if you are also experiencing head throbbing along with this sensation, it may be worth monitoring and discussing with your physician. In the meantime, you can consider taking a mild pain reliever such as Acetaminophen 500mg to help alleviate any discomfort.
