I took one shot of Prolia in January of last year with no problem. My neuropathy got worse with painful leg cramps and burning. I have severe osteoporosis. I refuse to take another shot of any kind. My doctors are not happy, but suggested to increase calcium, eat more cheese and calcium products. I've had no side effects. And when I get hairline fractures they quickly heal. My next dexa scan in in October, so we shall see.
I'm sure your mom will be fine, but always check with the doctors.
