The more you have going on, the more chance you have for issues. Good luck on the needle. Palpate the area and see if you can feel anything. Not necessarily sideways but all angles. If it's in there you're going to have to seek medical help. I can't imagine a non invasive way to remove it unless it's near the top where you could grab it with a hemostat or tweezers. Make sure you sterilize the site as well as the instruments too.
