Bumped Honda Element against pole, drivers side door pops when opening?

So I was an idiot and bumped against a pole as I was pulling out of a drive through (this place has it in the worst spot ever). Car runs fine, alignment seems ok, no weird noises.

But unfortunately the drivers side door pops whenever I open it, but not close. It happens almost immediately.

Any thoughts on this? Easy to fix? Or maybe a ballpark estimate to how much to fix?

Any input appreciated!

Well are we talking it catches on the wing type "po" or what? If you want a GUESS i'll give you one if you want an ANSWER provide MORE INFO and a PICTURE!
