Hi to all, I explain my problem. I'm a 24 year old male and I had a very occasional use of cocaine for the past two years (I used it every 4-6 months). But the last time I used it (a month ago) I had chest pain and a sensation of tingling/electric shock in the arms. From that episode I already performed 3 EKGs that resulted normal but I started suffering of heart palpitations: now I can feel my pulse in parts of my body where I didn't feel it before. For example if I join my thumb and my index, I can feel the pulse between the two fingers, or I can feel it in the fingers if I cross my hands, or I can feel it between my feet if I touch them with each other. Obviously I don't want to touch that **** again! I just wanna know if I will have these sensations for the rest of my life or if they will go away sooner or later. Does anybody had a similar experience? Thanks in advance for your replies and sorry for my bad english. P.S.: I found these two articles about cocaine: https://www.livescience.com/48796-cocaine-heart-damage-undetectable.html https://www.journeycenters.com/news/cocaine-can-produce-serious-undetected-blood-vessel-damage/ Maybe the palpitations are caused by blood vessels damage like these two articles suggest?
