I do not feel pain in my back,or arms or neck. Its a stabbing pain in the middle of my breasts it doesn't go higher than my collarbones. At night is when i feel it the worst and mornings. i cant sleep in any position because it puts pressure and the stabbing pain gets worse. I like to do early morning work out and i cant because i become weak and the pain infers a lot. Through out the day the pain is still there but it starts to feels sore. I am a Dcup n 5'2 and thought that might have something to do with but i don't feel pain in my back or shoulders. Its been bout a month now some days are worse than others. Should i speak with my doctor?
