Sleeping at night with sore knees and not being able to sleep actually involves two aspects: first, sore knees; second, insomnia due to sore knees. In general, the causes of knee soreness are mostly seen in the young population due to normal physical development, joint strain, trauma, etc.; while in the elderly, they are mostly seen in osteophytes, arthritis, osteoarthritis of the knee, etc. If the knee joint pain is caused by other diseases, it needs to be treated by a doctor. 1, the knee joint needs to be examined by CT or MRI to determine whether there is fluid in the joint cavity, meniscal damage, osteophytes, etc. If there is any of these causes, it should be treated according to medical advice. 2, the knee joint needs to do a good job of self-protection, such as avoiding cold, keeping warm, and sleeping at night. Avoid walking and standing for a long time to avoid trauma to the knee joint; use a hairdryer to blow on the knee joint with hot air every day, and then pat the knee joint and its surrounding tissues with both palms with appropriate strength, which is a treatment for knee pain. Most patients are able to get relief from sleep after the knee pain is relieved. If insomnia does not improve effectively, then insomnia needs to be treated at the same time. Sedative-hypnotic drugs such as eszopiclone, alprazolam, diazepam, clonazepam, etc. can be taken orally, as well as Chinese herbal medicines and herbal tonics that have a calming effect on the mind.
