He frequently suffers from a runny nose, has a poor appetite for solid foods, and experiences itching under his thighs, although he remains active. What medicines should be given to treat these symptoms?

For his runny nose, saline nasal drops can safely clear congestion. The thigh itching suggests chafing or a fungal infection; applying a zinc oxide barrier cream or a mild OTC antifungal cream (like clotrimazole), while keeping the area clean and dry, should help. His poor appetite for solids is likely linked to nasal congestion; offer small, frequent meals and focus on hydration. Please consult a pediatrician before administering any oral medications, such as antihistamines or deworming syrups, to ensure correct diagnosis and safe dosages for his age.
