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 .
