iv had this exact same problem. im on week 10 of a test enanthate 12 weeker with finasteride and i developed a gard patch under my right nipple. i started on nolvadex and since then the lump has dispersed. i was going to get letro but the nolva did the job for me. im just hoping that the gyno doesnt come back during PCT when my hormanone levels are fluctuating!! mt advice - hit the nolvadex hard. i did 80mg, then 60mg then 40mg for a week then im now down to 20mg. good luck
