question: I am a 30 year old female with sharp pain in my chest. Its sharp and difficult to breathe.  I went to the doctor Monday due to lower back pain, nausea, and upper stomach pain and sensitivity to touch. He gave me cipro, my chest hurts and I am still nauseous. I'm feeling pretty silly sitting outside the ER for it to get bad but if its just acid its going to be a big bill. Should I wait to see another doctor before going into the ER? I'm athletic but just quit smoking after 16 years, high stress
