I have been diagnosed with 2 noncalcified nodules on left lung. One is 6mm and one is 5mm. There is also a 3 cm x 2 cm bleb on the same lung. Ct scan was conducted because I thought I had kidney stones. I have been very nervous since the diagnosis. They immediately scheduled pulmonologist appt.. I am going to that tomorrow. Some symptoms I have had for a while: chest pain, ice cold legs and feet, insomnia, fatigue, shortness of breath. I am a 25 year smoker. Any suggestions about outlook or diagnosis? What is the difference in noncalcified and calcified? I am getting contradictory information about the two. Oh, what the hell is a bleb?
