Constipation?

I woke up this morning out of my sleep because I have been sh*tting! I went to the bathroom and have had the worseeeeee stomach pains. My stomach was actually hurting so bad, I started to get hot. I kept trying to push and it was all a really soft, half liquid/ type of poop. Long story short, my buttH*LE is actually burning when I poop now.. and the stomach pains are intolerable 😩.. any idea on why this is?
