Why does the joint between the small arm and the big arm of my hand hurt?

Friend, you are still young, and I may not fully understand what I said, but since you asked, I'd better talk about it, I hope you can understand.

You are now in a long physical period, and your bones are developing rapidly, and your demand for nutrition is relatively strong. However, due to various reasons, many people have the problem of insufficient nutrition supply to varying degrees, that is, relative malnutrition. Can you understand? At this time, there may be growth pain, and its manifestations are various. Some people have joint pain inexplicably, while others have pain after exertion.

Therefore, I suggest that you don't exert too much force at ordinary times, otherwise it will be bad for the growth of your joints. The solution to this problem is mainly to supplement nutrition and provide sufficient material guarantee for physical development. Drinking more bone soup may help.

are you satisfied with my answer?
