My current cough hasn't been just over 3 weeks and I've had X-ray and ct scan next week. The back pain comes and goes, right in the middle of my back sometimes burning and sometimes an ache. The x ray showed no infection so it's not that but of course my lungs are inflamed, so is that that causes the pain and the coughing? Will it subside as this starts to ease off? I'm very very fed up, sorry!
