If the patient finds finger swelling when he gets up in the morning, there may be the following situations: 1. There may be inflammation of interphalangeal joints of fingers, such as rheumatism and rheumatoid arthritis, which can lead to multiple symmetrical joints throughout the body, and interphalangeal joints are one of the common parts of the disease. When you get up in the morning, the inflammation of this joint is often serious. After a period of activity, it usually reduces. One of the main manifestations is joint swelling. 2. There may be upper limb compression, which is often seen when the patient excessively lies on one side during sleep, or puts the upper limb under the head, which will lead to swelling and numbness of the distal limb due to poor blood circulation. 3. It may be caused by some unintentional trauma during sleep. During sleep, if there are some unintentional actions, the fingers will touch other hard objects, which will lead to soft tissue contusion, or swelling in the morning.
