A wrong intramuscular (IM) injection can manifest in several ways, depending on the specific error. Common symptoms include pain, swelling, and bruising at the injection site. More serious consequences can also occur.
Common Symptoms:
- Pain: Discomfort at the injection site is a frequent symptom. The severity can range from mild to intense.
- Swelling: Inflammation and swelling around the injection area are common indicators of an issue.
- Bruising: This happens when the needle punctures a blood vessel.
- Infection: Improper injection technique increases the risk of introducing bacteria, leading to an infection. Signs may include redness, warmth, and pus.
Less Common, but More Serious Symptoms:
- Nerve damage: Injecting into a nerve can cause pain, numbness, tingling, or weakness in the affected area. The sciatic nerve, due to its location and size, is particularly vulnerable during buttock injections.
- Abscess formation: A localized collection of pus may develop at the injection site if an infection becomes severe.
- SIRVA (Shoulder Injury Related to Vaccine Administration): This is a specific condition related to shoulder injections, causing persistent pain and limited range of motion.
Identifying the Problem:
It's crucial to distinguish between normal post-injection reactions and symptoms indicating a problem. While mild pain, redness, and swelling are common, persistent or worsening symptoms require immediate medical attention. If you experience significant pain, numbness, weakness, or signs of infection following an IM injection, seek medical help promptly.
Examples:
- An injection given too superficially (not deep enough into the muscle) may cause only mild discomfort and swelling, but one that hits a nerve could cause severe and prolonged pain and numbness.
- Infection at the injection site may be indicated by increasing redness, swelling, warmth, and the presence of pus.

- Reference 1 mentions bruising, swelling, and potential infection as symptoms of a wrong IM injection.
- Reference 2 lists bruising, swelling, potential infection, nerve ending damage, and abscesses as possible consequences.
- Reference 3 highlights sciatic nerve injury as a common complication of IM injections, particularly in the buttock.
- Reference 4, 5, 6, 7, 8, 9, and 10 provide supporting information on injection site reactions, complications, and the importance of proper injection technique.
