Hello Doctor Hope you re doing great. I have had throbbing pain in my head at times in last few months and i was on migraine medication. The pain has slowly faded away but i am left with feeling of heart beating in head, neck and finger tips. the Feeling grows stronger when after even slightest bit of physical activity and I feel a lot of pressure in head when i bend it. I also feel numbness in my left hand and feet.
Is it the same beating you feel when you have headache? What medications are you taking for migraine?  It can be a part of migraine. You may require an increased dose of your medication. If symptoms started after taking medicines then it may be side effects of medications.
