4 Year Old's Severe Rear Pains

First of all, when you say that she has made poop for the last two days, what exactly do you mean? If a person is majorly constipated, then they can still produce more runny stool (which is going around the harder stool during elimination). If by 'normal' you mean stool that has some decent consistency to it, then this is probably not your/her issue.

Have you looked to see if there was some tearing when she was finally able to have a bowel movement? If she is 4, she should be able to explain something of the pain. Ask her if it stings...

A completely different thought would be to ask her if she has fallen down on her bottom recently. It is possible to fracture a tailbone by landing hard on your butt. This is actually something that a child can do rather easily. Maybe ask her when she noticed that it was hurting and what she was doing at the time...

- broken tailbone
- anal fissure/ cut or split on her rectum (common after large BMs)
- yeast infection (rectums get them, too!)
- bruise/hard landing
- pimple

If she suffered a slight tear during a difficult poop, that can not only hurt like hell, but can cause additional painful spasm of the sphincter muscles. I've been there, and anal fissures are fairly common in children. If it continues, please have a pediatrician check her. It's very hard for a parent without medical training to identify a tear inside the rectum.

What was the size and texture of her poop two days ago? I suspect it was large and hard since she was constipated. She could also have had a difficult time pushing it out. All of that would make her anus hurt. Have you looked at her anus to see if it's red and irritated? It may also have a small tear but even if there is no sign of damage just having been stretched will cause pain for a few days.

You can put hemorrhoid cream on and a bit inside her anus. It has an anesthetic in it. Or just wait a few days for it to heal.

I'll bet she hurt her tailbone. I did that when I was in middle school. Talk about painful! You should take her to the doctor about this.

Put her in a nice warm bath...she probably hurt her butt when she had a hard BM. I used to nanny a little girl who had such a hard time pooping and she would always say her butt was hurting. She would cry, it was awful! Make sure she is drinking plenty of water and high fiber.

Could be chafing, or she could have hurt her rectum when passing a large BM. Just put a little petroleum jelly on a q-tip and apply to that general area. That will help protect any tears or chafing.

What does the doctor think?
If it lasts more than 3 days, I would call and have her checked..

So many possibilities..

In addition to Riley's recommendations, she might have pinworms, which is easily treated by your MD/pediatrician.
