Spine has been hurting me

So a month ago i was flipping on my snowboard (nothing really big), i was about 8 feet up and i had that 1 in a million were the rotation wouldnt happen and i landed on my shoulders.but not arched backwards, more in the tucked position. 3 days after or so my middle back on my spine started hurting me. its only when i bend backwards and its in the same place. It doesnt hurt when i bend forward orwalk around for that matter. Now its not the kind of a pain were you break something... Any ideas?? Im just concerned because wakeboard season is coming and i am just a big fan of flips.
