Hi, Yes, doctors do recommend you wear a mask when outside. I am not sure what you mean by "outside" but I am assuming outdoors in the open environment?They will tell you to wear a mask if there is dust, grass, tree clippings flying around. That is where the aspergillous is. Or go indoors during those times. But sometimes that is not possible. When driving in a car with windows down and you pass a construction site. Or after tx, when you are taking one of your great walks, for miles and enjoying the outdoors and the fact you are alive, and you are walking your dog who just wants to kiss you, and you come upon someone mowing their lawn.... what should you do? Put on the mask for a minute till you past the offending stuff that is being thrown into the air.Wearing a mask is not that horrible really. I know pre tx, I could not stand the thought, because the lack of O2. But remember you have new lungs. It is much easier. Others I know are worried about "how do I look?" Well you look like someone who either has an illness that you do not want to spread, or you look like someone who is protecting yourself. If anyone asks, tell them. It is a great opportunity to talk about organ donation and transplantation. I rather enjoy wearing my mask when I am in a crowded area, on a plane, at the pharmacy, at the docs office, because inevitabley, someone is going to ask. I think of this as an opportunity to help others who are waiting organs to get the word spread and upping their chances of getting organs sooner. Also, wearing a mask is sort of fun. The funny comments "did you just rob a bank?" "Mom why she have a mask on?" "Does she have a mouth?" are actually great ways of meeting people. And to single men and women, here is a story. I was at a smoke free bar on St. Patricks Day ( actually all restaurants and bars and public places in New York state are now smoke free). The place was packed wall to wall. I was with a friend that had a lung tx a couple months before me. She is single, I am not. She had no mask on, I did. You know why she was not wearing a mask, concerned no guy would talk to her, approach her with a mask. She went to the bar to get our drinks, I just hung out. While she was gone for about 5 minutes, I had about 4 guys, or groups of guys come up and talk to me. About 4 of them were still hanging out and talking to me. The owner of the bar came over as well, and we discussed the CF "Run Like Hell" 5K race that the bar hosts and which I participate in. My friend came back, some of the guys moved on. I told her how many guys had come up to me, and I think the mask is a GUY MAGNET. She did not go for it, but I continued to be talking to people asking nicely why I had that mask. It is a conversation starter. I will share when I was leaving the bar, there were a couple of guys near the door, and I heard one say to the other "what the hell is she doing? what is her story?" Sort of laughing at me at the same time. Well, I am a very brave person since tx and not afraid to approach anyone. I stepped over, got into their personal space, which is much closer than I would ordinarily get to some stranger and said " have you ever heard of the flesh eating disease?" Their eyes widened, they took a step back ( which they could not do, since they were against a wall) and said with trembling voices " Yeah" I stepped closer and said " I HAVE IT!" And walked away. My sister reprimanded me when I told her. She said I should of first pulled the mask down and coughed on them, then told them the good news of what illness I had!!!!NEXT TIME!!!Hope that answers some questions about the mask.JOanne
