Chronic Uteceria. Be angioedema hives.

I had hives problem when i was a child . but over the years it had subsided. then in 2011 it appeared again so i took antihistamine tablet for a few days and it subsided . den in 2013 it appeared again . i did the same took cetirizine and it stopped again. now since 2016 January i have been getting severe hives all over my body with swelling of lips and palms and eyelids below the eyes. i did IGE test and it was found that I'm highly allergic to tomatoes ,milk, dog danger, capsicum, dust mites ,amoxicillin and sulpha. I stopped all that .. did panchkarma Ayurveda therapy .am presently taking Ayurveda medicine but no effect . doctor is suspecting it to be angioedema hives .Did all my test like LFT, USG,,hepatitis test, haemoglobin , all is normal. kindly advise
