Which symptom is commonly associated with lymphedema?

1. Painless swelling in only one limb

2. Skin rash in the affected area

3. Edema extending from toes to the groin

4. Frequent bruising of the legs

The correct answer is: Edema extending from toes to the groin

The symptom that is commonly associated with lymphedema is painless swelling in one limb. Lymphedema typically presents as a localized accumulation of lymph fluid that leads to swelling, often occurring in one arm or leg, but it is important to note that the swelling does not usually extend from the toes to the groin in lymphedema cases. In contrast, lymphedema is characterized primarily by its gradual onset, dependent on factors such as injury or surgery to lymph nodes, rather than a sudden or extensive swelling pattern as suggested in the choice of swelling extending from toes to the groin. The swelling tends to become more pronounced after periods of inactivity or standing and can vary in severity throughout the day. Painlessness is a hallmark characteristic of the swelling, as lymphedema usually does not present with acute pain, distinguishing it from other conditions that may affect the limbs. Thus, the key feature of lymphedema is the localized and painless swelling often seen in one limb, rather than swelling that extends from the toes to the groin.
