On Wednesday, the 52-year-old revealed a picture of a long scar on her back. She got it after surgery for an infection that ended up paralyzing her from the neck down.

Miller had to go through ten rounds of chemotherapy and said it took her months to sit up and crawl.

She currently has to use a wheelchair to get around but says, "maybe with a miracle someday I'll walk."
