In the clinic, we often encounter mothers or grandmothers who have wrist pain from taking care of their babies. This disease is called tenosynovitis of the wrist, and the medical name is “radial stenosis tenosynovitis”. Mothers often need to carry their babies, breastfeeding, milking, over time are prone to this disease. Doctors abroad often refer to this disease as “mommy’s hand” in common parlance. Hormonal changes are a common cause of the disease. In women, it often occurs around the time of pregnancy, childbirth and breastfeeding. Hormonal changes can lead to edema and increased pressure in the tendon sheath, making it more likely to develop tenosynovitis due to strain. In China, it is usually the elderly who help their children take care of their babies, which can be called “grandmother’s hand” or “grandma’s hand”. When the wrist is subjected to repetitive or continuous exertion, excessive friction and strain between the tendon and tendon sheath can lead to localized sterile inflammation, peritendinous congestion and swelling, increased pressure within the tendon sheath, and reactive thickening of the tendon sheath. When this occurs, any movement that requires sliding or force on these two tendons in the wrist will cause severe pain on the radial side of the wrist. If you have wrist tendinitis, you can apply heat to the wrist and topical ointments to relieve pain and reduce inflammation in the early stages or if the condition is not serious, but the most important thing is to get adequate rest for the wrist. It is useful to wear a wrist brace to help reduce adverse force on the wrist and to help the inflammation subside. During the acute period of tendonitis in the wrist, it is best to do less or no housework, not to hold children, and to use as little force as possible on the wrist that hurts. If you really need to hold a child, you need to pay attention to adjust the method of holding, is to use the other side of the wrist does not hurt to hold, the painful side of the elbow force, so that the wrist and fingers are free, to maintain a relaxed state, not to exert force. Most people can gradually get better through conservative treatment and proper conditioning.
