What happens when you hit a nerve when giving an injection?

When you hit a nerve during an injection, it can cause immediate sharp pain, tingling, or numbness in the area supplied by that nerve. This is often referred to as a "nerve injury" and may lead to temporary or, in rare cases, permanent nerve damage. Additionally, injecting into a nerve can result in complications such as inflammation or further pain. It's essential for healthcare providers to be trained in proper injection techniques to minimize this risk.
