I have a resident at work, age 65 over, who basically baths in Bengay due to aches n oains. She now is complaining of burning eyes, coughing up phlem, neasua, and not able to sleep. She blames this on cigarette smoke from another apartment but we are a nonsmoking building. My eyes burn and my sinuses clear instantly when entering her apartment. Could this be caused by the bengay fumes in apt?
