What Would Happen if I Get an Injection When Im Not Sick?

Needle injection is often used as a treatment for various diseases. However, it is clearly inappropriate to inject drugs into a healthy body as it can not only reduce the immune system's strength but also potentially cause allergic reactions. Doctors will not administer injections when a person is healthy, except in irresponsible small clinics.

1. Impact on Appearance: Many people experience allergic reactions to needle injections, leading to various skin issues such as redness, bumps, blisters, and pimples. These symptoms can have a significant impact on one's appearance and may also affect their work and daily life.

2. Decreased Immunity: Different individuals may react differently to various substances. Some people may be allergic to pet hair, pollen, or even the drugs injected during needle injection. If these allergic reactions are not properly managed, it can lead to a gradual decrease in the body's immune system.

3. Heightened Anxiety: Many people fear needle injections, and experiencing allergic reactions can further exacerbate their anxiety. This can create psychological barriers and adverse reactions such as dizziness during future medical treatments.

1. Intramuscular Injection: Administered into the muscle tissue, commonly targeting the deltoid, gluteus maximus, gluteus medius, gluteus minimus, and lateral thigh muscles. After routine disinfection, the needle is inserted at a 90-degree angle to the skin, reaching about one-third to two-thirds of its length. Once no blood is withdrawn, the medication is slowly injected. Intramuscular injection has a longer onset time compared to intravenous injection but is still one of the fastest ways for drug efficacy besides intravenous injection.

2. Intravenous Injection: Administered into a vein, typically selecting a vein that is easy to puncture, has rich blood flow, and is far from venous valves. After routine disinfection, the needle is inserted at a 15-20-degree angle into the vein. Once blood is withdrawn, the angle is reduced, and the medication is injected slowly. Intravenous injection is the fastest way for drug efficacy among all injection methods.

3. Intradermal Injection: Administered between the epidermis and dermis, commonly on the middle of the forearm's palmar side. It is often used for skin tests (such as drug allergy tests) and as a precursor to local anesthesia. After disinfecting with ethanol, the needle is inserted at a 5-degree angle or parallel to the skin, injecting 0.1ml of medication. The needle is withdrawn after a small bump forms on the injection site, without rubbing or pressing the area. For drug allergy tests, the results are observed after 15-20 minutes, and a 2ml syringe and epinephrine are prepared. Note that intradermal injection should not be disinfected with iodine tincture; if the patient is allergic to ethanol, saline can be used instead.

4. Subcutaneous Injection: Administered into the subcutaneous tissue, commonly on the lower edge of the deltoid muscle, abdomen, and inner thigh. It is often used for vaccinations. (Taking the injection on the lower edge of the deltoid muscle as an example, the skin is first disinfected routinely. Then, the syringe filled with medication is inserted quickly at a 30-40-degree angle to the skin, reaching about one-third to two-thirds of the needle's length. After confirming no blood withdrawal, the medication is injected slowly. The needle is withdrawn, and the injection site is pressed with a cotton ball before quickly removing the needle.)
