Every bruise should become smaller in one week after it appeared. Once the bruise completely disappears the pain should be gone, too. If the pain still exists it is possible that damage to the bone might be present.

It seems likely that the absence of big pain indicates that the bone is probably not broken. But this cannot be ruled out for sure without an X-ray. It is possible that even if there is no fracture, the X-ray might discover a bone fissure.

Given your age, it might be a result of osteoporosis, which should be treated immediately after the bone problem. Osteoporosis is a condition in which the bone density is decreased due to demineralization. The decreased density makes the bone more susceptible to fractures which is the first and only symptom of osteoporosis. Therefore, prevention is very important for osteoporosis.
