Lego Hands: Understanding the swollen, stiff fingers of pregnancy

“Lego hands” describes swollen, stiff, and numb fingers during pregnancy caused by edema from increased blood volume. While common and usually normal, sudden swelling with headache, vision changes, or unilateral leg swelling can signal preeclampsia or a clot, so seek medical advice. Management includes wrist splints, ice, gentle hand exercises, avoiding prolonged arm hanging, reducing salt, and physical therapy if carpal tunnel worsens; symptoms typically improve after delivery.
