Backaches have a variety of causes, the common ones being ruptured disks, skeletal irregularities and muscle strain, according to Mayo Clinic. Smoking, obesity and working in sedentary environments are the primary risk factors for this pain, notes Healthline.
Disks cushion bones in the spine and keep them in place. Sometimes these disks rupture, causing nerves to compress, resulting in backaches. Backaches can also occur due to skeletal irregularities, in which the spine curves abnormally, reports Mayo Clinic
Sudden, awkward movements, poor physical condition, and lifting heavy objects are the common causes of muscle strain. Ways of preventing backaches include maintaining proper postures, losing weight and exercising the muscles in the back and abdomen, says Healthline.
