1. Pat the inside of the elbow to get a rash. 2. Apply the whole arm with a wrung hot towel and wring it out! Don't get wet, you can also use a hot water bottle. 3. Soak your hands with safflower boiling water, at least in the middle of your upper arm, where you wear short-sleeved clothes. 4. Exercise, stretching your hands horizontally, palms up, and slowly rising to the top of your head, which is the most commonly used action in yoga. Stick to it and try it. There should be at least 70-80% improvement. No, find a professional health center to recuperate! Prevention is better than cure. If your body tells you, you should respond well! I wish you the best of health!
