My four year old daughter always have tonsilitis. She had just recovered from it for the past 3 weeks and now it is starting again. I'm so much bothered because she has a congenital heart disease (pulmonary & supravalvar stenosis) and I've heard that frequent tonsilitis is not good for the heart. We are currently living in qatar and I guess this has something to do with the dust here. How can I prevent and cure her tonsilitis? Please advise
