What causes the fingertips to feel sore, painful, and swollen upon waking up every morning?
Recently, every morning upon waking up, I feel soreness, pain, and swelling in the pads of my fingers. May I ask what could be the cause?

It is possible that the soreness and swelling in the fingertips upon waking up in the morning may be caused by multiple factors. The main causes include the following:
1. Improper sleeping posture: Prolonged pressure on one limb may hinder local blood circulation, thereby causing soreness and swelling in the fingertips.
2. Poor blood circulation: Impaired blood circulation may lead to obstructed blood return, leaving fingertips in a state of oxygen deficiency and causing a feeling of soreness and swelling.
3. Overuse of hands: For example, prolonged typing, mobile phone use, or engaging in heavy physical labor may cause fatigue in the hand muscles and joints, resulting in morning pain.
4. Arthritis: Conditions such as rheumatoid arthritis or osteoarthritis—inflammatory diseases—can cause joint swelling, pain, and stiffness, which are particularly noticeable upon waking up in the morning.
In response to this situation, it is recommended that patients initially attempt to change their lifestyle habits, reduce excessive hand use, and maintain appropriate rest and warm compresses to alleviate symptoms. At the same time, performing moderate finger stretching exercises can help improve blood circulation and joint flexibility. If symptoms persist or worsen, prompt medical attention is advised.
