Back pain in the morning, but can be relieved after waking up. Generally, it is considered to be related to the incorrect posture of sleeping at night, or due to the wind and cold during the night sleep, or due to the high pillow and the mattress being too hard or too soft. A soft mattress makes the spine unsupportable, and when combined with an incorrect posture at night, the muscles in the back are always in a state of tightness, so the back pain will occur in the early morning of the second day. After waking up in the morning and moving around, the muscles in the back will be relaxed and the pain will be relieved. After the back pain occurs in the morning, it is recommended that the patient maintain a correct standing or sitting posture in daily life, and the pain can also be relieved by appropriate localized hot compresses and massage, without taking medication.
