I have osteoporosis, and three compressed fractures. should one keep working or is resting better while healing?

Rest if recent.: If the fractures occurred in the recent past (1-2 months) you should avoid stress to the back. Generally healing and a reduction in pain takes 2 months. A bone density test should be done as medication is likely to be needed. Even after healing care should be taken to avoid stress to the back such as twisting, bending and lifting heavy weights.
