People have to eat and drink when they are alive. As long as they eat and drink, there will be shit. If all the garbage of human body can't be discharged in time, it will be deposited at the lowest end of human body-feet by the gravity of the earth, which will hinder the qi and blood of meridians and lead to insufficient supply. In addition, there are six meridians on the foot surface: spleen, liver, kidney, stomach, gallbladder and bladder. When Yang Can can't metabolize moisture, moisture will always find an outlet, and that is the foot. Massage these acupoints more when you are free, and keep soaking your feet every day, so that the meridians are unobstructed, which will be good for the heart, liver, kidney, spleen, stomach and gallbladder. Exercise more to keep a good mood, don't worry about getting angry, eat a balanced diet, and pay more attention to the changes of blood pressure, blood lipid and cardiovascular and cerebrovascular diseases. Also pay attention to whether there is a red dot on your big toe. Are you numb? Because these symptoms are the precursors of stroke and cerebral hemorrhage. In addition, see if the urine acid is high. If it is high, it is gout. Take your father to the hospital sometime, so that you can rest assured. I wish your father health!
