question: Hi earlier on today I accidentally mixed harpic toilet cleaner and bleach in my toilet and whilst cleaning it the fumes were very strong and I struggled to breath for a bit. the fumes subsided and I carried on but have since then felt like I have a bad cold and hs brought on a dry cough and now this evening I can taste blood at the back of my mouth when I cough. will this exposure to the fumes have a long lasting damage/effect on my lungs?
