I recently started dry coughing very bad for over a week.then glands swallon(淋吧)肿, then teeth infected, and one side cannot bite.
I went to see doctor today, they told me I am very low in immune system. how to improve my immune system?
I live a healthy lifestyle, not a couch potato, try to run every night, and try to eat healthy.
What else I can do? I am close to 50, female.
thank you.
