Osteoporosis, Arthritis -- my mom's poor health. Help.

So my mom's been a cosmetologist for over 30 years. She spends long days standing on her feet which has resulted in knee surgeries, carpal tunnel, spine curvature, you name it. Well I'm trying to get her to stop working so her health doesn't decline further (she's 54 but seems more like 80). What I'm worried about most is her Osteoporosis and Arthritis in her spine. Certain days it's really painful for her. What can she do naturally (besides cortisone injections) to help relieve or even heal these issues? Has anyone successfully improved bone issues?

Thanks in advance!
