Ok About 6 Months Ago I Put Off A Bug

Ok About 6 months ago I put off a bug bomb in my house I aired it out but soon after my cheeks got red and I had aloof swelling in my lower legs and forearms tingling then my ears began to ring all the time . My head began to feel full and full of pressure....I could not stand it I left my home . I had a job at Sams club as a food demonstator and my ears were full of fluid. I have been to the doctor 3 times ... They put me on steroids which helped the swelling of arms and legs but I still have a slight buzzing in my ears and head pressure with dizziness in the morning....
