Hives returning like this after delivery are usually allergic, often tied to a specific food, and postpartum hormone shifts can make skin more reactive for some weeks. The rash moving around your body with no breathing or facial swelling fits a typical allergic flare, not an emergency.
Next Steps
Avoid the beef fry and kalka roast for now in case either triggered this, and note anything else you ate just before it started. Please check with whoever prescribed Levohal-M before restarting it, since a breastfeeding-safe antihistamine choice for your newborn's age needs their review, or a dermatologist's.
Health Tips
Go to the hospital right away if you get lip, tongue or throat swelling, breathing trouble, or the hives spread very fast.
