If you find that your back is sore and uncomfortable after being in bed for a long time, it may be because you have been in bed for too long and the muscles have been compressed for a long time causing soreness; or if you have lumbar muscle strain and other lesions, you may also have soreness and discomfort after being in bed for a long time. In addition, there is degeneration of the back itself, such as osteophytes. The time of bed rest can be reduced appropriately, and local hot compresses and massage can be given. If the soreness is more obvious, you can apply creams such as flurbiprofen. Getting up and moving around, together with hot compresses and massage, can soon relieve the soreness. If the pain is persistent and uncomfortable, it is necessary to go to the hospital in time to see a doctor, combined with physical examination to analyze the cause, if necessary, to improve the X-ray examination of the spine, to understand whether there are obvious bone lesions or osteophytes in the spine and other problems.
