A few weeks ago I used a powerful cleaner in one of my kitchen cupboards which was given to me by someone, but I then realised it was an oven cleaner! Since then whenever I go into the kitchen I can smell something that makes me feel really dizzy, my sinuses have been constantly inflamed and ive been all puffy and swollen around my sinuses and have suffered constant headaches, nausea and light headedness. Despite having antibiotics to try to clear this up I still have this problem, could this be related to me using that cleaner as surely the fumes would be gone by now?
