I was going down the stairs last Saturday when I suddenly slipped, I don t remeber how I fell, I just knew I was suddenly sitting and I was choking. I grabbed my brother s arm and tried to tell him I couldn t breathe. He started pumping on my chest til I was able to get some air again. After the incident, my ribs & back hurts, my left rib cage is hurting more than the right. I m having a hard time getting up or even looking at the back, it s like my upper body couldn t even rotate sideways. My heart is also hurting whenever I bend down and I lose breath. Whenever I laugh, cough or sneeze, there s a sudden pain in my back and ribs. Should I have it diagnosed? Or it s just normal for people who fell down the stairs?
