Recently, I played boxing. Now my left and right hands hold the muscles under the little finger hard, which hurts. I don't feel strong enough. Do you want a quick cure? Pray for the great gods.

Don't think that everything can be cured quickly. Fast is not necessarily good, nor is martial arts.

One of the more appropriate methods is to relax properly when making a fist, so that the fist can have strength, and the strength of maintaining tension will be greatly reduced; There is also a towel soaked in hot water. Just apply it before going to bed every day, and it will naturally ease in a few days.
