I agree, with the others, maybe not enough exercise or an irritation causing an issue. It may not necessarily be a bean, other things can um, get stuck up there. I did Cin's first cleaning (since I owned him) about a month after getting him. He didn't have swelling but was acting really itchy. WELL, I didn't find a bean, but I did find an old, gross, nasty straw wrapper, one of those plastic ones from a kids juice box, stuck way the heck up there! So now I don't think there is any end to what a horse could possibly get stuck up there.
If you find nothing, then maybe a 15 min to half hour trot or more on a lunge line may help.
If it starts smelling funky, or having discharge, I would get a vet though.
