I was admitted to the hospital in March with adelectisis in my Right Middle lung.  I was treated with atb and steroids as I am a severe asthmatic.  It appears that the adelectisis is actually getting bigger.  I feel fine besides the severe back pain and I am very tired as I cant sleep d/t pain.  Since this is getting bigger should I worry about Lung cancer. I am a non smoke, but was raised by two heavy smokers. My dad died of cancer of the Lung and my mom died of ovarian cancer.
Atelactasis is failure of small bronchiole to inflates there is blockage there is less supply of oxygen to parts and lungs leading to pain as you describes as it grows it causes more problem need to take bronchodilator spy TDS antiallergic once a day and liquid antacid take pulmonary rehabilitation exercises for lungs and short courses of steroids and other supportive therapies
