I feel for you hun, mu daughter in law had a very similar experience happen to her. In fact the doctor had to reinsert the biopsy needle 4 times before he got to the position he could withdraw from. She was in horrific pain for quite sometime afterwards .. she bled and bruised badly. When she returned 6 weeks later, she was still bruised; hmm, he seemed ashamed that he had done that to her... as he should be.
She since has changed doctors and sees a woman; the office has pain relief sessions and follow up care as Jaybay has stated. Follow up with someone hun... pain is not something you should have to deal .. especially due to stupidity.

When was the biopsy done? You might consider calling the docs office and asking the nurse about post-biopsy breast care and what other palliative methods you can use to get the pain under control. You may just have enough swelling going on that it's putting pressure on a nerve and causing the shoulder, arm and neck pain. Nerve pain is notoriously difficult to treat, but if you can get the swelling under control, it should go away.
I haven't had a biopsy myself, but my sister and another friend had a similar experience to yours. It took a couple weeks for everything to calm down.
