I am a 20 year old male. I have a constant pricking pain in my heart. I feel like a prick with the knitting needle and also like a spark or an electric current in my heart. It started this year and occurred very randomly. I have stomach cramps, and sometimes I feel like my esophagus has liquid in it. My health record is clean. My blood health record and blood pressure are alright. I do not understand what is wrong with me. I am in a state of panic. Please help.
