Help! Back Pain From Trampoline?

Can somebody help me?

• I am 12, and when i was on my friends trampoline in may , i did a flip and it went wrong, i landed strange and couldnt move because i was in so much pain, but 10 mins later i was ok, and could walk, weeks after my back constantly ached,and if i stood/sat still for about 10 minutes it would ache even more for about 1 hour, but now if i bend backwards my back feels like its ripping, and still aches!! The injury was in may! im worried i have done some bad damage to my back, can anyone tell me what i have done to my back? How i can fix it? and if i went to the doctors what would they do?? Thanks for any help.
