Key Questions Answered
Spinal discs absorb fluid overnight while you sleep, which temporarily increases their height and alters the mechanical loading of the spine. Combined with hours of muscular and joint inactivity, this process causes stiffness and discomfort when you first get out of bed.
Occasional stiffness that eases with movement is common, but you should seek medical attention if pain is persistent, repeatedly interrupts sleep, takes a long time to settle, or lasts more than five to 10 minutes. Prolonged stiffness can sometimes indicate an inflammatory condition like ankylosing spondylitis, an infection, or other underlying spinal disorders.
A medical assessment typically begins with a review of your medical history, followed by a physical examination to check spinal movement, muscle strength, sensation, and nerve function. Doctors may also inquire about the pain pattern, whether it wakes you at night or spreads to your legs, and recommend imaging tests like X-rays or MRIs if clinically indicated.
