My 79 year old Mom tripped and fell over a blanket on Monday. The x-rays at the hospital were inconclusive as the ER doctor thought her foot was broken but radiologist said it was sprained. They wrapped her foot and put her in a walking boot and said to take her to an orthopedic after a week if it wasn’t better. The boot is causing a great deal of discomfort for her especially during the night as she is sleeping. Since it’s a “walking” boot, can she take this off while in bed?
