"I’m at high risk of a fall of course."

I use a rollator which is a walker with 4 wheels and comes with a seat. There are many styles and price points to choose from. I would think insurance would pay for this type of medical equipment if a doctor wrote a prescription for it.

I remember a doctor telling me how painful it looked when I walked. I denied that it was painful but said it hurt when I walked too much. She said I needed a walker. I protested and said, "I never fall." She escorted me to the physical therapy department and told the therapist I needed a rollator. I wasn't sure what a rollator was but I assumed it was something to prevent falls. I reminded my doctor that I will never fall. She said the rollator wasn't to prevent falls but she wanted me to have one to "keep me mobile."

As much as I hated the rollator at first ... it has become my best friend. I can walk as far as I want and sit down whenever I need to. You aren't supposed to use it like a wheelchair but I can scoot around a bit while sitting if I need to.

The greatest thing is my rollator never complains about carrying my bags for me when I travel!
