Hi, a friend of mine is in a great deal of pain from his left Kidney. He went for a CT scan last Friday and was later told there is no infection just and Air Bubble causing all the pain and that it would go on its own. He also mentions a word not sure if I have it right Anoma He was also prescribed antibiotics and was told this will help the air bubble to go away. Where did this Air Bubble come from and what is the best treatment to get rid of it? Thank you
