Which of the following is a common symptom of lymphedema?

1. Pitting edema

2. Redness of the skin

3. High blood pressure

4. Muscle cramping

The correct answer is: Pitting edema

Pitting edema is indeed a common symptom of lymphedema. It occurs when excess lymph fluid builds up in the tissues, leading to swelling. When pressure is applied to the swollen area, an indentation may remain for a short period of time, which is characteristic of pitting edema. This type of swelling is associated with conditions that cause fluid retention, but in the context of lymphedema, it indicates lymphatic system dysfunction. The fluid retention in lymphedema is typically more persistent and can lead to skin changes and further complications if left untreated. Other options like redness of the skin, while it can occur in lymphedema, is more commonly associated with infections or inflammatory conditions rather than being a primary symptom of lymphedema itself. High blood pressure does not relate directly to lymphedema and is a separate condition often influenced by cardiovascular health. Muscle cramping may occur due to various factors, including fluid imbalances, but it is not a defining symptom of lymphedema. Understanding these distinctions helps to clarify the hallmark characteristics of lymphedema, with pitting edema being a key indicator associated with this condition.
