... chest before. I am getting a bit worried because as the day has gone on it seems to be getting worse. I would not say it was pain it just feels so uncomfortable. My oxygen level seems to be fine, blood pressure too. I know not to panic because it will just make the symptoms worse, but I am wondering if MS is playing a big part here. Happy New year to everyone and I hope 2012 is a healthy and pain free year. Thanks Liz
