There are many reasons why a patient may experience swelling and pain in the finger joints after getting up in the morning, such as rheumatoid arthritis, which can affect the small joints of the fingers, resulting in swelling and pain in the joints, and in severe cases, deformation of the joints. In addition, when the patient sleeps, the upper limbs are pressed for a longer period of time, or the finger joints are cold for a longer period of time, which can affect the local blood circulation, resulting in poor blood flow, stagnation of Qi and blood stasis, and obstruction of meridians, and the patient gets up in the morning and has swollen joints. Patients may also experience this phenomenon due to chronic strain and strain on the finger joint area during the day, resulting in damage to the joint capsule, muscles and other tissues in the joint area.
