Injection

An injection is the act of administering a substance, typically a medication or vaccine, into the body using a syringe or needle. This method is commonly employed in medical settings to deliver drugs directly into the bloodstream, muscles, or under the skin. Injections can also refer to the introduction of a substance into a system, such as a fuel injection in an engine, emphasizing the concept of adding something directly to a specific area.

Patients are often apprehensive about injections, but understanding the process can help alleviate anxiety and ensure a smoother experience.
