Awww that just stinks @Jax1964 .
Biopsies in general are just the pitts. Both of my core biopsies I nearly jumped off the table when it made that big clicking sound, even though they warned me it was going to do it and not to move. Probably why the first one missed LOL.
I've never had a biopsy under mammogram but I did have the hookwire checked with that after they put it in via u/s. That really wasn't too much fun considering it was still terribly bruised from the previous 2 bx's.
All fingers and toes crossed for you for it just be a cyst. xoxoxoxo
