Changes with Age. In most cases, a person's normal respiratory rate will change with age; younger adults, children, and babies will typically have faster respiratory rates, because as people age, their breathing usually slows down.
Modic changes are pathological changes in the bones of the spine, the vertebrae. These changes are situated in both the body of the vertebrae and in the end plate of the neighboring disc.
In addition you need to be in the hands of a clinician who recognises the clinical syndrome of Modic-related back pain described above, i.e. someone who can differentiate your pattern of pain from the normal backaches that affect us all. That is to say it is like many diagnoses in medicine.
