A three-year-old child has a cold that just won't go away. What should be done?

Patient's question:

No

Doctor's answer:

Considering the poor constitution and weak immunity, you can receive intramuscular injection of gamma globulin or take protein powder to boost your immunity. Traditional Chinese medicine treatment can be adopted, or it can be combined with pediatric massage. If the condition allows, bloodletting therapy can also be very effective.
