Hi For the past month I have been having chest pains that seem to come and go. Since Saturday they have gotten worse. I am now experiencing a “pins and needles” sensation in my face, hands, and feet. As well as nausea, vomiting, stomach pain, and slight arm and jaw pain. I am a 27 y/o female. I have been to the hospital twice and they have ruled it was anxiety after an ekg but the problem has been persistent and not gone away. At my last hospital visit they had prescribed me Xanax, which is now finished, and the pains did not even subside with those. Today I have experienced the worst pains yet and now shortness of breath. Any advice on what I should do or if this could be something more serious?
