Breast implant & difficulty breathing

Hello, I’m thinking to have my breast implant after two months, I did many tests for ( blood, heart, breast ) and Im normal, but I’m very nervous that sometimes I have difficulty to breath like I can’t get enough oxygen specially If I was in closed room with many people, or if I selpt on my left side, and from bra too, so I’m nervous if I have a breast implant this could affect negatively on my health, although all the test I have done show I’m fine <_>
