I am preparing for neet pg... completed my MBBS this year..i am suffering from allergic rhinitis since 15 years and also chronic sinusitis .. I have severe pain and tenderness on palpating my sinus...also painful eyes.. and headache.. I have tried all sorts of medicine which we use..I am now planning to take immunotherapy ie allergic vaccination for house dust mites.. which I'm allergic to.. Sir/madam... It will be very kind if you could give an idea about the vaccination..it's success rate.. and is it really worth taking.. my studies are badly hampered due to health. Thank you
