Hives appears on body after delivery.

Hello Doctor, I am 10 days postpartum after a C-section and am breastfeeding my newborn baby boy. I developed hives during my first trimester of pregnancy and previously took Levohal-M for around 3 months, which helped control them. Now the hives have returned. The itching started on the backs of my hands, and later the hives appeared on my chest and other parts of my body. The rash moves from one area to another, and the itching is currently mild and improving. I suspect food may have triggered it, as I recently ate restaurant beef fry and homemade kalka roast. I currently have no breathing difficulty, facial or lip swelling, or other emergency symptoms. Could you please advise what may be causing these recurrent hives and which medication is safe for me to take while breastfeeding a newborn? Should I restart Levohal-M or use another treatment? Thank you.
