What should I do if I get sick while traveling to America?

Self-help travel must buy insurance, which is not expensive. In case of emergency, you can see a doctor nearby and don't take medicine indiscriminately. Pharmacists in pharmacies can only give you OTC drugs. Real drugs need a doctor's prescription. Tour groups are generally insured, so don't worry. You can bring some common medicines, such as digestive medicines for colds and colds, but you can't bring too much, otherwise it will be difficult for the customs to explain.
