If there is no improvement or other symptoms appear, you should go to a regular hospital for treatment in time to avoid self-diagnosis and misuse of drugs.
Professor Wang from the Department of Vascular Surgery at Peking Union Medical College Hospital mentioned in a recent health live broadcast: "The color changes in the palm of the hand can indeed reflect some health problems, but it needs to be comprehensively judged in conjunction with other clinical manifestations. If a tiger's mouth is simply blue, after traumatic factors have been ruled out, it is recommended to check the microcirculation status first."
