I fell of my bike training for a triathlon, broke two vertebrae, L1 and T11. I have been given a three point brace and am trying not to bend forward due to the compression fractures. I am normally fit and healthy, only take beclametasone for controlled asthma. 6ft 3inches, 73 kg, pulse at rest 42 to 44 age 52. Have developed a chest infection and am coughing up green mucous. I will seek medical help and get antibiotics. It only started this morning. The actual question I have is that coughing is VERY painful. Can it further damage the existing compressions or create new ones. I do not have osteoporosis and there is no family history. Thanks in advance
