Hello, experiencing soreness, pain, and weakness in both legs is a very common phenomenon and one of the frequent chief complaints reported by patients in clinical practice. In elderly patients, soreness, pain, and weakness in both lower limbs are most commonly caused by degenerative osteoarthritis—for example, affecting the bilateral knee or hip joints. Following degenerative changes in these joints, the surrounding muscles and soft tissues are also affected, thereby impairing lower-limb mobility and leading to symptoms such as soreness, pain, and weakness. We hope the above information is helpful to you. Wishing you a happy and healthy life!
