Pneumonia and now CT scan

[MrsOK]

I'm hoping someone can help me. I had community acquired  pneumonia at Christmas 15 for the first time which required 2 nights hospital stay. Prior to this if not had any real health issues, ex social smoker ie maybe 2/3 cigarettes every couple of weeks for about 8 years until about 13 months ago. 7 months later I got pneumonia again (still recovering now 3 weeks later). So my local hospital referred me to a lung specialist due to my age (33) previous medical history ie no medical problems as they said it was unusual someone of my age to get or unknown once, never mind twice. Anyway I saw the consultant at exactly 3 weeks after the pneumonia diagnosis and 3 different antibiotics (clarithromycin, co-amoxyclav and another one beginning with T - can't remember!) anyway I had an X-ray and the consultant has said there is an abnormality on my lung and I have a CT scan booked tomorrow and follow up with the consultant on Tuesday. So now I am really anxious and getting worried that I have lung cancer or something. Has anyone ever had similar and had a CT scan and it's all be ok, ie lingering pneumonia or scarring etc? I am worried beyond belief and it feels like a long wait until I find out. Any insight or pay experiences  would be greatly appreciated. I almost forgot to add, I am 3 weeks past pneumonia now and I have pleuritic pain on the right side where the pneumonia is/was and I have a sore left shoulder. Apart from that I have no other pneumonia symptoms. I didn't have a cough with the latest episode of pneumonia.
