Kelly had used social media to thank the many people who'd prayed for her during the operation, saying their prayers had 'worked'.

However, Thursday morning, she posted on Instagram that she had gone back into the hospital after experiencing excruciating headaches when her pain meds were decreased.

In an earlier Instagram post, Kelly had described how difficult it was to be the 'mom she wants to be' for her children at this time, due to the physical, emotional and mental effects following surgery.

Kelly noted that she's hoping to return home tomorrow. Read her Instagram post below:

"I thought I could do it. They told me tapering off the steroids was going to be very difficult. The first picture was yesterday when I was on what I thought was my last day of steroids. I thought I could power through the pain and massive headaches that were challenging me throughout the day. I figured i could pull my strength from one of the strongest people I know, Matthew. I told myself the pain would succumb to me, I wouldn't succumb to it.

I was so wrong. The pain got so far ahead of me I couldn't keep anything down, including meds. I ended up in the ER very early this morning, back on steroids and pain medication. At first, I felt like I had failed, like I couldn't handle it.. but what I really failed at was listening to my own body. A lesson I feel like I am going to have to keep reminding myself of.

Thank you again for everything. I just wanted to give a little update. They will keep me here overnight just to monitor in hopes of going home in the morning." Subscribe for free to Breaking Christian News here
