Mycoplasma infection can also cause cold symptoms, such as nasal congestion, runny nose, sneezing, headache, fever, muscle pain, coughing up phlegm, and difficulty breathing. Mycoplasma infections tend to have a long course, which can lead to persistent coughing that is difficult to resolve and requires examination. If it is confirmed that there is a mycoplasma pathogen in the body, it can be treated with macrolide antibiotics administered orally or intravenously to reduce inflammation. After a course of treatment, re-examination is necessary. Drinking more water and resting more are essential for recovery. Additionally, smoking and alcohol should be avoided.
