Hi thanks for contacting health care magic..... You have inhaled cleaner of bathroom like diluted acid ..... Here only chest tightness was present and now feels better .... So no need for worry about that.... It might be by irritation of respiratory mucosa. Take rest.... Smoking and dust exposure kept limited. Excess spicy and fried food like irritant avoided. Wear mask while driving for few days. If you feel cold antihistaminic drug taken. If chest tightness increasing with difficult breathing consult pulmonologist to rule out bronchitis. The doctor will do chest x ray and spirometry to rule out bronchitis and its severity according to which treatment given. Take care
