<s>[INST] Im constantly having a pulsation, palpation, jumping feeling in different parts of my body. It feels like a heartbeat. Im not sure if its in my veins, arteries, or muscles. Im 29, sedentary, normal blood pressure, and cholesterol. My dr. said everything seems to be fine. [/INST] DearWelcome to ChatDoctorWe understand your concerns went through your details. I assure you everything is fine. You know blood travels through veins and arteries. You will be able to feel pulses wherever thick arteries are available. Head, neck, shoulders, arm, wrist, thigh, stomach sides, knee, calf, feet etc. are areas where which arteries are present. You could feel the pulsation at all these places. If you obsess with these pulsations, you will become anxious and your heart beat increases due to the anxiety. Please donor misinterpret it. Your doctor told nothing is wrong with you. Accept it and be happy. Take care.  If you still need my assistance in this regard, please use this link. http://goo.gl/aYW2pR. Please remember to describe the whole problem with full detail. Hope this answers your query. Available for further clarifications. Good luck. </s>
