I am trying to help my friend , who s daughter is showing symptoms of transient unilateral axilla and breast swelling . It is very painful for her , she is only 14 , and just started menses. The transient swelling has been happening for the last year , seemed to have begun after a family trip to the carribean , they thought it was possibly an infection , but no results after 3 courses of antibiotics. Patient has had breast exams and when the swelling is down , nothing is felt by physician. Does this sound immunilogical to you ? Could it be autoimmune , mum suffers from crohn s ,? thanks
