I have been taking dutasteride (Avodart) for three months and now my breasts are very tender and sometimes sore.  Just yesterday the shoulder belt in the car made me wince.  This is a ~1% side effect based on the packaging.  I am wondering whether I have won the "booby prize" in the "1% side effect lottery"  and will experience further breast growth as a result.  (I am not on any other meds.)

Have any of you had experience with breast tenderness and/or growth from just Avodart or Propecia (finasteride)?   

I was taking it but it was along with E so I can't say yes or no.  But it is a side effect.

I was on propecia for a year, followed by a year and a few months of avodart when I started taking a very tiny dose of spiro, and I had actual budding start after a month of the two together. According to my doctor it wasn't possible, til he felt me up. I dont really remember my breasts changing any on the avodart by itself, but I didnt pay much attention to my body at those times.
