<s>[INST] I scrubbed my basement floor with bleach water about 5 hrs ago. It took me about 20 minutes and after words I got a heachache and felt sick. Symptoms seemed to disappear and now after sleeping for a few hours I have a burning sensation in my chest up to my throat and I am nauseous. What should I do? [/INST] It is due to the inhalation of toxic fumes of bleaching powder. It will give you a little irritation for a couple of days if you are not an allergic person. However if you are an allergic individual, it can trigger asthma and severe Bronchospasm. Take a tablet of pantoprazole 40 mg and an antacid syrup 2-3 times daily for 2 DAYS. </s>
