I also think that you need to see your doctor and get some tests done, nothing is definite until you do so. It’s very scary not knowing what is happening but the only way to deal with it is to get more tests done, a ct scan is just the first step and then you can move forward and get all the information you desperately need to put your mind to rest, good luck to you and for what it’s worth, you’re not alone and many people here including myself have gone through the same thing so we’re here for you,

I'm not a doctor. You need to ask your doctors and be vigilant. Just worrying about it won't do you any good. If it bothers you, you need to talk more to your doctors. Getting second opinion never hurts either.You need to get more tests done to more definitely say anything about it.

Are you seeing a pulmonologist? That’s who did my biopsy on a spiculated nodule. Please continue to pursue a complete diagnosis.
