I am 14 and I am on a 3 tablet, 10 mg for 5 days dose of prednisone to treat pneumonia. I was on the same dose this August to treat pneumonia as well. Before the first pneumonia, I was 5'4" 104 pounds, and now I've ballooned it seems, to 127lbs. but I only eat 1,500 calories a day on average. is this normal? and is it normal to get severe pneumonia twice within 5 months? please help me
