Message: [QUOTE="vietnow, post: 1353007, member: 107539"] I need help, I went to jump on semilone,Fl and I only been riding for a month mx bikes I use to do road race. It was my 3rd time there at the track and there was a tall jump so I accelerated on 3rd gear and did the jump when I landed I did not fell but right when I landed I got a big pain on my mid back and could not breathe, I then waited a little like 10min and I was breathing ok but having a lot of pain on that place right now. What could I have done wrong? What does it make that happen and what can I do please help. [/QUOTE]
