APEA Predictor Practice Exam

The key distinction between sciatica and a herniated disc centers around their definitions and the symptoms associated with each condition. Sciatica refers to the pain that radiates along the path of the sciatic nerve, typically due to irritation or compression, often linked to underlying issues such as a herniated disc. When a patient experiences sciatica, they may find that standing or walking alleviates the discomfort, as these positions can relieve pressure on the nerve. This is why the option stating that sciatica feels better when you stand is accurate. In contrast, a herniated disc may not always lead to leg pain, and it might not always result in an improvement of symptoms while standing. Additionally, while sciatica can worsen with sitting, that symptom doesn't define the condition itself but rather outcomes arising from nerve root irritation due to various underlying causes, including disc issues. Understanding these aspects clarifies why standing might provide symptom relief for sciatica specifically, setting it apart from just the presence of a herniated disc.
