Often in the practice of medicine, we encounter many patients around 60 years old, who complain of sinking back pain, take X and CT films showing osteoporosis, and then the doctor diagnoses osteoporosis on the basis of the imaging report, but the treatment with anti-osteoporosis drugs for some time still has no effect, after which the doctor and the family do not care about the treatment, but often at this time you as a doctor think more about a diagnosis, multiple Myeloma, whether to do a few more tests, such as this week’s protein, but this test can not confirm the diagnosis, can then perform bone penetration test, perform this test, can basically determine whether it is multiple myeloma, so it is recommended that doctors are thinking a little bit more. For reference only. As a patient, you should also pay a little attention to your own health.
