Talk to Dermatologist on Red Patches On Lips

AOA. Plz help me out. I have recurring red patches under my lips. It started from eid. Pehle chaley howe jo bht zyada hogaye the or khane peene main takleef hoti thi. Phir uske baad eid se red patches hote hain sirf lips k ander. Jo bht zyada takleef wale nahi hote lekin uncomfortable se hain. Like khana peena asani se hota hai khane main koi takleef nahi hoti or yeh red patches 2 ya 3 din hote hai. Phir khud hi khatam hojate hain or dosri baat k yeh sirf lips tak hi rehte hain phelte nhi. Maine ek do drs ko dikhaya kisi ne kaha k weakness ki waja se hain baby ko feed kam karao ( mera baby 8 months ka hai or shoro se main use on demand feed krwati ho) or diet achi lo. Plz muje bataye k mujhe kiya karna chahye k yeh bilkul khatam hojaye baar baar na ho. Sorry for long post.
