What causes a feeling of fullness and pain in the calf?
The child doesn't like to eat vegetables and often is a picky eater. Now the calves frequently feel swollen and painful—why is this happening?

Calf swelling and pain is a common symptom that may be caused by various factors.
1. Lower extremity varicose veins: This is usually caused by genetic factors, poor lifestyle habits, etc. Symptoms often include calf swelling and pain, numbness, and protruding blood vessels.
2. Lumbar disc herniation: This may be caused by strain, trauma, long-term poor posture, and other factors. Lumbar disc herniation can compress nerve roots, causing symptoms such as calf swelling and pain and muscle weakness.
3. Overexertion and strenuous exercise: If a patient engages in excessive physical activity, heavy labor, or intense exercise, it may lead to lactic acid buildup in the legs, resulting in swelling, pain, and other adverse reactions in the calves. Symptoms can generally be improved through appropriate rest and local massage to promote blood circulation.
4. Malnutrition: Poor dietary habits such as picky eating may lead to malnutrition and calcium deficiency, which can also cause calf swelling and pain.
5. Soft tissue injury: A direct impact or compression to the calf may cause soft tissue damage, leading to calf pain.
