I Fell 20ft From The Second Story Of A Warehouse,

I fell 20ft from the second story of a warehouse, I was up in the loft that the owner built inside his warehouse. He showed me where some boxes where that he wanted me to get, and then he left
I didn't know that's the rest of the floor was actually a hanging ceiling . It was dark and to me looked like the rest of the floor, so when I put my leg down along with the box, I fell through the cieling , I got caught in some cable wires for a second then it gavre out, I continued falling down to office below me, I got a desk with my foot trying to break the fall then finally hit the ground and landed on my side . I didn't break anything, but I am sore everywhere especially my chest and my back. It feels like I am bruised down to my bones, it hurts to laugh, cough or breath .At first I thought I was healing but the real pain 20 days later! I can't get comfortable in any position, the pain is constant. I went to emergency they gave me pain killers, that are gone now. And did a scan of my upper chest. What is going on inside my body with such pain.
