There is an old man in my family who often coughs, has excessive phlegm, and is short of breath and chest tightness! Easy to catch a cold! Extremely weak! Help Chinese medicine remedies!
In other words, coughing doesn't have to be a cold or a fever. Chest tightness, spitting, chest tightness, cough and other symptoms are all symptoms of upper respiratory tract. (If there is nothing wrong with the heart)
I suggest you: first go to the local regular hospital to do a mycoplasma examination, find out the reason and treat it. Second, often go outdoors for physical exercise, such as jogging, kicking shuttlecock, etc., to enhance physical fitness and resist the invasion of viruses.
Third, keep a good attitude, don't be bitten by a snake once, and be afraid of straw rope for ten years.
Fourth, you can take orally the traditional Chinese medicine of clearing lung-heat, resolving phlegm, nourishing heart and enriching blood for two weeks. I think it will take a while.
Finally, I wish you a speedy recovery and happiness every day!
