Oh Red, How wonderful NO cancer!! Prayers have been answered! I am so happy to hear that you must be so relieved!
I am sorry about the safe person and the breathing issues, let me know what the chest x-ray shows, I had a chest x-ray last month because of breathing, it could be SO many things, a little broncitis, or a temporary reaction to the anthesia, I spelled that wrong I am sure, I hope as you read this it has let up, I am glad you are home and cozy in your home and resting well.
My Doctor and Mother-in-law both told me when you quit or cut down on smoking you cough MORE, its your lungs getting rid of the nicotine, which is good, I think your lungs are just recooping! I have cheated a few times the last few weeks, I have had a couple cigarettes and I am SO mad at myself, but I have cut down to almost nothing! My primary said its the "dopamine" in the cigarettes, My husband bought me an "electronic cig" it helps, its hard, I know its very hard to quit Red.
I do not think you have congestive heart Red, my Dad had that and there are a lot of other symptoms, he lived with it throught and died of something else years and years later. I am so glad you are home. Sending you healing angels, please let me know how you are doing.
