Hello S96s and thanks for posting,

I am sorry to learn that no one in A&E gave you an explanation before sending you home and can understand why this would bother you.

The A&E department should be getting in touch with your GP to let them know what the test results showed and depending on this, if anything needs to be done. So I think the best thing to do would be try and find out if your GP surgery has had a summary about you yet from A&E. 

My understanding is that shadows can occur for a number of reasons for example cysts (fluid filled sacs), so try not to worry. But I think it is very reasonable to want to know what this is all about so do be sure to follow it up yourself with the GP. 

I hope your GP can help. 

Wishing you the best,

Julia
