I have had problems with pollens, perfumes, scented candles, soaps, detergents, etc for my whole life. I ve never found a way to treat symptoms. My only way to prevent symptoms is to avoid triggers except that I can not control other people s clothing, perfumes & products, and homes. Recently, I ve been dealing with the neighbour s laundry venting into our suite, causing panic attack symptoms. I have chills, shaking, dizziness, narrowed vision, headaches, problems breathing, nausea, I can taste the detergent, heart racing, difficulty thinking and speaking, my eyes sting and start watering, my throat is dry and burning, my vocal folds start grating with vocal fry. I ve been panicking, and withdrawn. My neighbour washed my towels without asking and now I ve tried washing them 6 times and I can smell the detergent when I walk by the towels. I have two small children and it s impossible to parent them when my body feels under attack. Is there any medical advice to treat symptoms? Would antihistamines help would this? I would hate to take an antihistamine every time I encounter a trigger.
