Pulsating fingertips. It was synchroniz!

Is it normal to feel pulsation in fingertips if you press your finger against an hard surface, i havejust noticed it 3-4days back and now it had become quite annoying, consulted a cardiology,and neurologist but none explainedme what is happening one of them straight up said to have an color Doppler, also i had my ecg with echocardiography done one and a half month back so im guessing it not releated to heart still, once i had my bp shoot 150/100 due to some reason so i thought this might be due to bp when i checked my bp came 128/72 , in short i dont if it Something serious or not, please guide me because now its getting quite disturbing and is hindering my daily tasks, and also can it be the samepulse that the pulse oximeter reads when we use thedevice and i have just become a little sensitive towards it, because ifi dont press it anywhere i dont feel any pulse its there only when i press my fingers against a hard surface, and its definitely pulse as i counted it and it was synchroniz
