Talk to Pediatrician on "Tonsils And Fatigue

Symptoms and History: Chronic Fatigue: I feel exhausted all the time and have no energy for daily tasks. I feel like sleeping throughout the day. Low Body Weight: I am very underweight and feel physically weak. Chronic Tonsillitis: I suffer from recurring tonsils. My throat is extremely sensitive; if I consume yogurt, bananas, or a cold milkshake, my throat gets infected immediately. Seasonal Sickness: Every year, at the start of the summer season, my health deteriorates significantly Recent Treatment: I recently received an injection for my throat/weakness, which provided some temporary relief. Main Concerns: I want to increase energy levels, but I cannot take high-calorie shakes or cold dairy because of my throat issues Requested Advice: Kindly suggest how I can improve my immunity and gain weight without triggering my tonsils. Also, what tests should I get done to find the root cause of this constant fatigue?
