Allergic problems, chest problem arises.

Need a proper allergic disorder treatment. I have visited to doctor and tested for IGE test and got the value 232 in report. now doctor says that he will do a test of rupees 18,500 for 110 allergies to diagnose whether any allergen is causing problem. Doctor said if there will be any allergy from allergen then he will give vaccine Allergen immunotherapy worth 7,500 only for 4 months and so said that i will treat but i don't guarantee of treatment. I myself personally over last 1 year researched on allergic disorder and came to that allergen immunotherapy should be given for atleast 3 years to be effective than how come a 4 month allergen immunotherapy can disappear my symptoms completely?...Please help me to to treat my disease and try to tell about the vaccine treatment to completely get cure and live like before
