Back pain from lung problems

I forgot to tell you. Last Friday I woke up with a pain in my back where my lungs are. I thought it was because of the way I slept. I wasn’t hungry all day and, in the evening,, I was feeling weak like I was getting the flue. Then I realized the pain in my back was actually my lungs. I could feel it when sneezing or deep breathing. I took 3 drops CD and again 6 before bed (in 120 ml water). It wasn’t gone in the morning but also not worse. So I took another 6 right after I got up, 1 hour later 3 and another hour later again 3 drops. After that it was gone, I felt better and hasn’t come back.
