Stafford's wife back to hospital as post-surgery pain persists

Kelly Stafford checked herself back into the hospital on Wednesday because of pain following brain surgery. The wife of Lions quarterback Matthew Stafford posted on Instagram that she needed medical help to cope with headaches and other side effects. She had a 12-hour operation last week to remove a brain tumor and returned home Sunday.

"I told myself the pain would succumb to me, I wouldn't succumb to it," Kelly Stafford wrote in the post. "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."

She said she would be held overnight for observation and hoped to return home Thursday. ESPN's Adam Schefter reported that Matthew Stafford returned to workouts with the Lions on Monday but that the team has told him to take whatever time he needs to assist his wife.

The Staffords are parents to twin girls who turned 2 last month and an 8-month-old daughter.
