For patients with osteoarthritis, hot compresses are very effective. Hot compresses can promote local blood circulation, which can effectively alleviate the clinical symptoms of osteoarthritis. Usually, hot compresses are applied using hot water bottles, or by heating bran or salt, which are very effective. Typically, apply the hot compress twice a day, each time for more than half an hour. Additionally, aside from hot compresses, it is important to protect the affected area in patients with osteoarthritis, avoid exposure to cold, and reduce irritation to the area. When necessary, treatment may also need to be supplemented with medications, such as pain relievers and drugs that nourish the cartilage.
