Mesenteric lymphadenopathy. Paneer?

My son 5.8 years, From Aug 2023, is frequently down with cold, cough and fever with his paed prescribing nebulisers (duolin, budecort) and inhalers(foracort). On jan 11, he first complained of stomach pain but I ignored as we were travelling. Pain was once in 2-3 days. he again got fever for 2 days, cold and cough from jan 22nd and was given syrup omnacortil forte from jan 30th as his cough didnt reduce with nebuliser. He got constant stomach pain from feb 3rd and we went for usg which stated mesenteric lymphadenopathy with largest 10.3*7.3 mm in right paraumbilic region. He is currently on antibiotics taxim o forte for 7 days, lanzole and biogermina. We are on 4th day of antibiotics but There is no reduction of pain . He feels pain after meals for 30 secs to a min. No fever, weight loss for now. Will this go away with antibiotics ? Any diet n physical activity restrictions? He likes paneer, chicken but I have stopped all this. He is craving for paneer. Can I give homemade paneer?
