. Constant backache , what is the cause of this ?

Not Medical Advice: A constant backache or constant back pain could be attributed to many different causes, including acute kidney failure, kidney stones, muscle strain, broken or fractured shoulder blade, dermatomyositis, H. pylori infection, hydronephrosis, kidney infection, osteomyelitis, pulmonary embolism, vertebral compression fracture (lumbar or thoracic), tick bite, endocarditis, or shingles.

In fertile females, back pain can also be due to a miscarriage. If back pain is occurring in an older adult age 45 and over, it may be a symptom of renal cell (kidney) cancer.

Causes of backache and back pain can vary widely due to a number of different circumstances, including whether the pain is sharp or stabbing vs. burning or stinging pain; severity of pain; whether pain is in one or both sides of back; if pain is made worse by pressure or movement; whether pain is made better with ice applied; and whether there has been recent injury or trauma associated with the back.
