Hey Guys so I went to the ER for 2 things today. The usual shortness of breath which turned out to be bronchitis and a lump I had on my tailbone that I had for about 4 weeks now which turned out to be a cyst. My question is was anybody ever given an oxygen mask? I was given an oxygen mask and after it seemed like My chest got so tight. Anyways I was given an inhaler and antibiotics. I just used the inhaler and it seemed to help a little. I also just drank maalox. Anybody else have this issue? I don't smoke or anything.
