There are several common causes of vague pain in finger bones: the first cause is due to acute injury or chronic strain resulting in local congestion, edema, and inflammatory reaction resulting in impaired blood circulation, increased tension in the bone and abnormal sensation, and vague pain. The second cause can be seen in bone tumors, which can cause increased tension in the bone due to the growth of bone tumors, occupancy and extrusion, resulting in vague pain. The third cause is vascular disease, which is caused by abnormal vascular circulation, resulting in poor local blood circulation leading to blood stagnation and irritation, resulting in vague pain. The fourth reason is that the finger has been subjected to adverse physical and chemical stimuli, such as cold, sudden cold, sudden heat, and humid environment stimulation can produce vague pain symptoms.
