<human>: Summarize the given text in a few sentences.

I have never had one, or had anything up my pooper. I have been backed up since Christmas, with only a little bit of bowel movements passing by. An x-ray done showed I had a lot of fecal matter in my intestines, and after drinking Magnesium Citrate, Luculose, and Miralax, nothing has helped pushed it out. I've just expelled liquid. I'm on my way to an Urgent Care center right now, to be administered an enema. What do they feel like? Will I be in a lot of pain? Is it as embarrassing and anxiety ridden as I feel it is?
<bot>: About to get my first enema in half an hour. Scared and embarrassed for myself. What has been your experience?
