Frosted glass nodules can swim. There is no need to be overly alarmed by the discovery of ground-glass nodules on physical examination, as most ground-glass lung nodules are benign nodules caused by pneumonia and tuberculosis. If they are accompanied by obvious clinical symptoms, such as cough, sputum, fever, etc., it is recommended to carry out anti-infection and anti-tuberculosis treatment first. After treatment, ground-glass nodules can shrink or even disappear. However, there are some nodules that do not disappear completely and do not cause clinical symptoms, so regular checkups are needed to observe the changes in the nodules. In addition to regular checkups, people with ground-glass nodules can also do appropriate exercises to improve their immunity. Swimming is a healthy form of exercise, which can not only provide whole-body exercise, but also improve lung capacity. Therefore, people with ground-glass lung nodules can also swim.
