In the outpatient clinic, we will see some pregnant women who may have some various kinds of discomfort, and some of them may say that their hands are usually easily swollen. In fact, from the orthopedic point of view, there may be many reasons for the occurrence of edema in pregnant women. This is just like a river, there may be reasons for the upstream, middlestream and downstream of the river. Swelling of the hand is equivalent to a problem downstream, and to find the cause, we have to look for the upstream, midstream, or downstream itself. For example, cervical spondylosis may appear and then cause soreness, numbness, swelling and pain at the distal end of the limb, and swelling is one of them. Midstream, for example, peripheral nerves, such as the plexus, ulnar, radial and median nerves, problems with these nerves may also cause swelling of the hand. The lower reaches of the river are the hands themselves, which can also be swollen if they are overactive or cold, or if some sterile inflammation occurs. However, it is important to note that pregnant women, a special group, the hormone levels in her body are different. Many people may have some limb swelling due to abnormal hormone levels in the body, and this time it is often not only hand swelling, but also other parts of the body may be swollen. Therefore, if a pregnant woman has swollen hands, not only from the orthopedic aspect to find the cause, but also from other aspects to analyze the problem, so that we can make a comprehensive judgment, scientific diagnosis, and avoid some omissions and misdiagnosis of the situation.
