intermittent left sided upper chest pain

for the past week i have been having intermittent chest pain in the upper left side of my chest near the top of my breast. at some points when i feel this pain, it will be sharp and take my breath away. I have not been to the doctor for financial reasons. it goes away sometimes as quickly as it comes. when it starts to go away, it is a dull ache through out the area of my breast and feels crampy. I am not on any medications, I have normal labs (last time I went to the doctor) and I do have polycystic ovary disease. when I press down on the upper part of my breast and when I take a deep breath I can feel it more. I cannot distinguish whether or not it is my breast that is feeling the pain or my actual chest.
