<human>: Could you distill the essence of the text into 1-3 sentences?

I've actually had one of these questions in the back of my head for the longest time, but I didn't know if it was appropriate to post it here. Now I've got a second one, though, so I figure I'll bundle 'em together and it'll be fine.

1: Sometimes I pull the roof of my mouth. I know it sounds weird, but that's the best way I can explain it. I'll swallow, and some crazy how the roof of my mouth hurts when I swallow from then on, for a while. In this state, swallowing drink still hurts, but is way less painful than actual food matter. I haven't really found a way to ease it so I just have to force down the rest of my meal. My question(s): What am I doing/how am I doing this, and how can I avoid it/get it to go away?

2: This is kinda dirty but it's something that I realized makes no sense to me. You know when you have a lot of poop, it hurts? So you go to the bathroom and you fire off your first volley. "Ahh," you say to yourself. "Now the pressure is gone and the rest of this poop can be pain-free." I guess my question is, why does it still hurt, and sometimes even more than originally? Obviously it isn't pressure anymore, and the best thing I can come up with is... suction? But I don't know.

Please, help me out, /r/askreddit!

(Also if I've posted this to the wrong subreddit please advise.)
<bot>: How do you avoid pulling the roof of your mouth; why do your bowels still hurt after you relieve pressure sometimes?
