For the last two winters I have had pneumonia. The most recent bout of it left me with nodules in the lungs, for which I have chest CT scans every six months. So far there has been no change in the nodules. However, during the last few visits with various doctors, they have told me that I have crackles in both of the lower lungs. Any ideas of what could be causing these noises. They say I am free of the pneumonia and all blood work has been fine.
If not lung related, this could be cardiac related. Has anyone done an echo? This is an ultrasound of the heart. If you have what is called "congestive heart failure", that would be causing crackles (which is a sign of fluid on the lungs). Are your feet swollen? Are you short of breath at rest?
My feet and legs do not swell and I have had the blood test for congestive heart failure which came back negative. Also, my cardiologist did a stress test and an echocardiogram, which were all fine. One doctor thinks it is scar tissue from the recent penumonia.
That's very possible, studies have shown that even when pneumonia is resolved residual damage is left. Make sure to help prevent future infections you should deep breathe and cough several times every 1 to 2 hours and especially upon awakening.
