Joint pain in the hands may be a symptom of diabetes complications, or it may be caused by other diseases such as rheumatoid arthritis. Diabetic patients may have symptoms such as excessive drinking, excessive eating, excessive urination and weight loss, etc., and diabetes itself does not cause joint pain; however, if the long-term blood sugar control is not good, it may induce diabetic peripheral neuropathy, which leads to pain, abnormal sensation and other symptoms, causing joint pain in the hands. In addition, other diseases may also cause joint pain in the hands, such as rheumatoid arthritis and osteoporosis. Patients with joint pain in the hands are advised to go to the hospital and ask the doctor to take into account the specific circumstances of the case to determine the cause of the disease and timely treatment.
