Nearly a month now since diagnosis with COPD and still feel stressed. X Ray clear but Spirometry test gave result of COPD. Yesterday and today I feel a burning between shoulder blades and ache at bottom of rib cage area of back. Also suffer from heartburn because of a hiatus hernia. No sign of infected sputum or coughing or cold although others in house have a head cold. Could aches be stress related or lung related or GERD related - any advice welcome. Lungs constantly on my mind!!!!
