Hi,
I am 24. Eight weeks ago, I noticed my breast started to swell. My left breast is now two sizes larger than my right breast. Three weeks ago, my left arm also swelled (slightly) and is very painful. My doctor said that it is fibrocystic changes, and should improve in a month or two. From what I've read, this does not match. Has anyone had a similar experience? Should I push for more testing? Thanks for your help.

Yes I think u should go for more tests!
