For a few months now, when I take a shower, I am experiencing problems breathing. It becomes overwhelming. I wind up opening up the shower curtain to finish taking my shower. I turn down the hot water, and even when it has been so very cold for winter mornings, I still have to open up the shower curtain to breathe. I don t understand this..... I have always been able to enjoy a warm or hot shower during the fall and winter. I have a bad back, and have enjoyed the hot water running down my back. Thank you, Cathy
