Try alternative medicine NAET and/or BRT, body restoration technique with a chiropractor that does applied kenisology. AK.
NAET does have a DETOX protocol to clear the body of allergies. Once you have completed the DETOX protocol to clear allergies form the system, the chiropractor will be able to help you with specific issues.
There is another method BAX 3000 and BAX AURA. This is done at a chiropractor that is more advanced with techniques and newer methods.
My husband and I have used all these methods with Extremely good results. In addition to allergies we have used for other issues such as rashes, viruses, bacteria, lung and cough, blood sugar, inflammation arthritis, metals, thyroid, CELIAC disease, and exposure to pesticides etc.
Our immune system has improved and so has our quality of life
Good luck
