How Should Intrinsic Allergic Susceptibilities Leading To Several Allergy Issues Be Medically Addressed And Cured?

Question: Hi, let me fill you in on my self-first: I am 60 years old, female. I have had a hysterectomy. Smoker 2 packs a day. Have tried to quit several times, but have not been successful. But the main problem is about 7 years ago I developed severe allergies. It started with sumac trees in my yard, which sent me to the hospital. Then I had several anaphylaxis episodes from the following list coconut, almonds, peanuts, apples, peaches, some chocolates, So basically I have tried to stay away from all nuts, and about the only fruit I eat is bananas and oranges, strawberries or any berries. I use Epi- pens, my family doctor wants me to go to a allergy specialist. He has me take a Pepcid and Zertec in the morning and Pepcid and Benadryl in the evening every day. Which helps, but not always. My problem is I don’t have insurance and I don’t have a lot of money. Just keeping epi -pens is really a strain on the family finances. I have read that the allergy testing is about 60 % accurate. That is to say about 60 % false positives. I just don’t have a lot of faith in it anyway. About 20 years ago I had seasonal allergies, I had insurance and went through the skin prick tests and It really didn’t help, that doctor put me on Claritin D which I could have avoided all the test and took it anyway. I read on every label, and try to be very careful about what I eat. But I keep swelling on my face and sometime on my body giant hives I take extra Benadryl and hope it works I only take the epi-pen when swelling is in my mouth tongue or throat. My question is can the allergist really help me or is it mostly just hype. I know that I am just finding out by trial and error what I am allergic to. But in the end isn’t that what a allergist will do?
