Hi! my wife, aged 61 yrs, was exposed to temperatures of minus 4 degrees last month, and, reportedly, developed' community acquired pnemonia. She was hospitalised and has been on heavy dose of antibiotics for 14 days, including 4 days through iv. She still feels discomfort/pain in her chest on the right side. A digital xray done y' day still showed patches and a' hump' on the right lung. What could be wrong and what treatment would you suggest? she' s a bariatic surgery patient since 2007.
