Well that's a bummer. Go easy for a bit and maybe take ibuprofen to get the swelling down.
The only real suggestion I have is to go to a clipless system that requires no additional effort when exiting like Crank Bros. Candy 3's. I use them on my fixie and they hold very securely, yet to exit all you need is a slight twist but there's no resistance at all. Easy to clip in as well with no fumbling at all since they're two-sided. Great pedals. I've even considered them for my road bike.
