The joint is located at the junction of bone and bone, including the joint surface, cartilage, joint capsule, ligaments, etc. When these structures have problems, they can cause pain in the joint area. When inflammation occurs, it is called arthritis. The most common symptom of arthritis is joint pain, in addition to morning stiffness, joint swelling, limited mobility, and joint deformities. Arthritis has a wide range of causes, with over a hundred different types, all of which fall under the category of rheumatism, including immune, genetic, metabolic, traumatic, tumor, degenerative, infectious and other types of arthritis. Therefore, if joint pain occurs, especially non traumatic joint pain, it is recommended to seek medical attention from a rheumatology and immunology department. Rheumatoid arthritis and rheumatoid arthritis are often confused, but their causes are completely different. Rheumatoid arthritis is a chronic arthritis that can cause joint damage, commonly seen in middle-aged and elderly women. It manifests as joint pain, swelling, and stiffness in the morning, often affecting finger joints, wrist joints, toe joints, knee joints, etc. It often appears symmetrically on both sides. Early diagnosis and treatment are necessary to avoid affecting joint movement and causing joint deformation. Rheumatoid arthritis is induced by streptococcal infection and does not cause joint damage. With the wide use of antibiotics, the incidence rate has become lower and lower. Osteoarthritis is the most common joint disease, characterized by degenerative changes that often occur in individuals over the age of 40. Common areas of pain include the knee joint, hip joint, and distal finger joint, which can also affect the cervical and lumbar spine. Gouty arthritis is caused by the deposition of urate salts in the joints, which is related to abnormal purine metabolism. Factors such as alcohol consumption, improper diet, and medication can all induce acute joint pain. The most common manifestation is redness, swelling, and obvious pain at the base of the thumb, which can also occur in other areas such as the ankle and knee joints. In recent years, there has been a trend towards youthfulness, which is more common in middle-aged men. Spinal arthritis is a type of disease represented by ankylosing spondylitis, which can affect the spine and sacroiliac joints. It often manifests as pain in the lower back and buttocks, and can also cause swelling and pain in joints such as the knee and hip. It needs to be distinguished from diseases such as lumbar disc herniation and lumbar muscle strain. The external environment is an important factor in inducing joint pain. In damp and cold environments, arthritis patients are prone to worsening joint pain symptoms, mainly due to defects in vascular contraction and nerve regulation function in rheumatoid arthritis patients, who are more sensitive to damp and cold environments. Rheumatoid arthritis patients experience reduced local joint fluid flow in damp and cold environments, leading to the accumulation of inflammatory substances in the joints, resulting in increased pain and swelling. How to protect joints in daily life? The most important thing is to develop a healthy lifestyle, maintain a regular schedule, ensure sleep, avoid infections, control weight, quit smoking and limit alcohol consumption. During the acute phase of pain, it is not recommended to strengthen exercise. Patients should take medication under the guidance of a doctor, and only after symptoms are relieved can rehabilitation exercise be performed. However, during the acute phase of pain, one should not be completely immobile and can do some stretching exercises appropriately. It is recommended to engage in rehabilitation exercises without joint weight-bearing to enhance muscle strength and maintain good physical function. Patients with ankylosing spondylitis should try to maintain stability while standing
