I dont have a final diagnosis yet.  I thought I was having rib problems, but when  they took xrays, my rib was fine and I appear to have swollen nodules on my left lung.  I have pain on the left side of my chest.  It started with a burning pain just under my left breast.  My left side is swollen from under my left breast around to to left side of my back.  I have the burning pain almost all the time and sharp stabbing pains occasionally.  They are going to do a cat scan, but I admit to being scared.  My step-father died of lung and liver cancer and it wasnt pretty.  It takes two vicodan at night to sleep.

### output:

Hi and thank you so much for this query. I am so sorry to hear about these swollen nodes in the lungs. Swollen lung nodes can represent a lot of different pathologies including tuberculosis, acidosis, cancer, fungal infections, etc. From the outskirts, we cannot make a conclusion, but we would bear in mind all the possible causes and investigate to identify the exact cause. Do you smoke? How old are you? Do you have cough? Where do you live? Etc. These are all further information that we would require to factor in and see what makes one more likely than the other. Please, I understand you fears, and they are real. No one would pretend not to be be concerned by such a finding. I however encourage you to stay calm and let's pursue the tests to obtain definite answers. What I know is what ever the cause, you would not be facing this alone. We promise to stand by you and provide you with the best possible care you deserve. I hope you find this helpful and it ad Chat Doctor.  Thank you so much for using our services and feel free to ask for more information and clarifications if need be. I wish you the best of health.
