Suffering with osteoporosis; at what point will I get real symptoms?

When a bone breaks. Unfortunately, osteoporosis does not have symptoms until you have an "insufficiency fracture." this can be a broken hip or wrist from a simple fall, or can be a compression fracture of the spine. Any of these would be associated with significant pain and disability - certainly serious symptoms. You should discuss medical treatment of osteoporosis with your doctor to prevent these fractures.
