Many people will feel uncomfortable here and there after a certain age, especially in the joints, in fact, it may be because of bone spurs, so what are bone spurs? After having bone spurs, the body will always have pain, so what are the specific symptoms of bone spurs?1. Pain is characterized by insidious onset, persistent dull pain, mostly occurring after joint activities, rest can be relieved. When sleeping, because the muscles around the joints are damaged, the protective function of the joints is reduced, and can not limit the movement that causes pain as when awake, the patient may wake up with pain.2, morning stiffness and adhesion to feel the morning stiffness of this disease is relatively short, usually no more than 15 minutes. Adhesion refers to the stiffness of the joints when they start to move after a period of time, such as sticking. Mostly seen in the elderly, lower limb joints, can be improved after activity. 3, with bone spurs may lead to deformity, instability of the joints, in the weight-bearing may also lead to pain. Because the anastomosis of the joints is relatively poor, and the contraction and spasm of the muscles have a certain effect, so there will be functional disorders. In weight-bearing joints, there is also a risk of sudden loss of function. These are the symptoms of bone spurs.4. Pressure pain and passive pain in the affected joints can be localized pressure pain, especially with the synovial effusion. Sometimes there is no pressure pain, but the pain can occur when the joints are passively moved.5, joint activity popping sound to the knee joint is common. Examination method: the patient sits, the examiner moves the knee joint with one hand, the other hand is pressed on the examined joint, and the clicking sound can be felt when the joint moves. It may be caused by the lack of cartilage and the lack of smoothness of the joint surface.6. Joint swelling can be caused by local bony hypertrophy or exudative synovitis, and in serious cases, joint deformity and subluxation can be seen.
