I've been having sharp chest pain and sharp pain and numbness and cold feeling in my arms and chest along with the sharp pain they keep saying nothing seems wrong I don't believe because they just been doing the same tests I feel like they should do a cardiogoniometry a (cgm) test because I heard that works better than a (ekg) but they said they don't know what that is and they won't keep at night for more tests and to monitor me I feel like they don't care and are just going to let me die
