Hi, I'm new here. Just recently diagnosed. I'm 58 and a smoker. My oxygen level is still at 100%. For now, I must quit smoking. I also have a lot of pain in my left rib, can't lay flat w/out pain. I hope to learn a lot about COPD here. So happy to have found this site. My Dr. is very nice but I'm very afraid and have a lot of anxiety and panic attacks. Thanks for listening.
