Any advice on sunflower seeds

I have been eating sunflower seed for some time now, and until a few week ago I didn’t have any problems. Then I did a very dumb thing, instead of just eating the shelled seeds I got a bag of seeds still in the shell and I guess I swallowed some of the hulls and they got stuck. I was in terrible pain for 3 days until they worked there way through. I do limit the amount I eat, like Scott said they are high in fat and calories.
