I had currently feeling burning sensation on my stomach. It is like gastric pain. Besides that, I used to underwent a surgery to remove cyst from my ovary. I realize I have been exposed to second hand smoker every time I analyse my health. I know stress can also be one of the reason of developing acidic in stomach. Can second hand smoker leads to gastric and other illness such as ovarian cyst? I have a manager who smokes in the office and not at smoking area where I am literally exposed to it quite frequent lately. I am quite stressed over this issue and I am so clueless how to tell him as I have given him the clue and he seems to unable to adhere to it. Please advice.
