Finger joint pain upon waking may be caused by compression or intense physical activity. During sleep, pressure on the upper limbs can restrict blood flow to the finger joints, leading to ischemic changes and resulting in joint pain. It could also result from excessive workload during the day or strenuous exercise. If the pain does not subside, methods such as warm compresses can be used to promote local blood circulation.
