since latter part of December I have suffered from back and chest pain-urgent care took xray because of pain and gave z pak and said look like COPD (I no smoke). follow up with my doc which ran a ekg and hospital for ct to check for blood clot or reveal pneumonia was gave levoguinn. never had a fever or cough but the back pain up and down spine really hurts. called doc back to look at scans again cause of continue pain an was told that it was from pneumonia but the right lower lob was the infected area but pain is on the left side of body. do you think it is from the levoguinn or how long is this going to last?
