Suggest Treatment For Anxiety And Pulsating Sensations In Buttocks

Hi, 21 year old man here. I was just curious as I have been dealing with anxiety and worry for the last few months in regards to worrying about my health and heart. I am experiencing a variety of symptoms which cross over with anxiety such as muscle aches, pains and other various symptoms. I m finding it hard as some symptoms cross over with me worrying about my heart but symptoms come and go away. I am active run every day comfortably with no problems eat well and am of a good weight for my size. I used to use cocaine for about a year and half on and off which has led me to believe that I have done some damage to my body and have worries about my arteries hardening maybe and what ever else. I experience pulses in various places such as in my bum after I got out the bath just when I was lying on my bed. I have had a chest x ray, blood tests done and my blood pressure at 127/70 which came back normal. Just wondered if you could shed any light or an opinion on what I m experiencing and whether you think it is more of an anxiety related issue?
