Hello Jeana, I have to agree with the other posters. In the past stress has paid a huge part on my bod and can effect a drop in my lung function. I once called stress my arch-enemy as I became aware ít' at times did prolong my recovery efforts from hospital stays. I used to worry about how my family were coping without me, sometimes no amount of their reassurance comforted me. I found the hospital had a great Social worker on board their health team. A problem shared can often become a problem halved. I also think it's ok to have a little stress in your life, I kind of feel life wouldn't be normal without it. In more recent years I believe it's how we handle or react to certain life challenges that triggers the dose of stress thats dished out. MamaScarlett touches on our already weakened immune systems, and this is really why we need to be careful. It's helpful if we can learn to recognise what emotional or physical factors that set the alarm bells off. Jeana, I hope the PICC line is helping and you are regaining some of that lost L/f. Yes, I'm a bit naughty I will definitely have a restful 24hrs prior to taking my spirometry test....I have found in the past, if I'm racing against time, this will effect my L/F result. Cheers Eileen.
