Thank you for writing.
This condition refers to bone mineral density, or BMD, that is lower than the normal peak BMD, but still not quite low enough to be considered osteoporosis. BMD is a measurement of the level of minerals in the bones, giving indication as to their strength and density. If you are diagnosed with osteopenia, it can mean that you have a greater risk, as time passes, for developing BMD that is low enough to be classified as osteoporosis.
Some people who are diagnosed with osteopenia may not necessarily have bone loss. They might just naturally have lower bone density. Osteopenia can also be the result of many other conditions, disease processes, or treatments. Osteopenia is more common in women than in men, mainly because women have a lower peak BMD and because hormonal changes during menopause speed up bone mass loss.
Ostopenia had no symptoms, really so this pain should not be connected. You need to discuss this with your doctor to find the cause.
