This happens to people who have cold hands for many years. Say goodbye when it's a little hot, and it will swell when it's hot. In summer, their hands are thicker than those in other seasons and they feel bloated. Because you haven't had it before, not necessarily because the blood vessels are thin and the blood circulation is slow. Have you done any hard work recently, or do you always do something with your hands in one posture, such as always holding a mouse or something? Or what did you drink at night?

I don't know if the joint hurts, so it's best to go to the hospital for a long time to do a microcirculation first, because if it is too expensive to do color Doppler ultrasound directly, and it is for the whole arm, the opponent will not pay much attention to it. The first problem is mainly the hand. I'd better listen to the doctor's mind.

Don't take medicine indiscriminately. Go to a regular hospital. Acupuncture should not be used indiscriminately. Don't leave it for long. If there is a small problem for a long time, it will become chronic and incurable.
