Last week I fell off my horse and landed on the right side of my back. It was sore but so was the rest of my body and it was bearable. I even took a PF test the day after and it didn't bother me. Yesterday my back really started hurting and today it's even worse. It hurts constantly, but just a dull pain, but when I sit down, stand, put my shoes on, bend over ect. It has a really sharp pain. I have a pretty high tolerance for pain but this has had me in tears. My mom says I should just push through it but it keeps getting worse. I am 16 if that helps. it is right side mid to low back. Could it take this long for a back injury to rise, and what could it be? Thanks!
