I cant even say for sure where the pain is located, I know just that i cant breath properly, that i have pain every time i try to breath.The pain started straight away, i dont drink, smoke, hade any surgery done or being hurt in any way.The pain started 5 days ago and it carry on.Yesterday i felt much better but with effort (folding some clothes) it returned.I dont know whats this pain!To be more precise, the pain is located on my left side, not in the front or back, just on the side, on the left side of my breast, but its not from the breast as it hurts inside, any time I try to breath more, i feel like something is squeesing my inside and it hurts badly.I was stressed lately and i thought it may be from this, but for so many days?Please help!Thanks
