Actually why was I not thinking, Today after the needle core biopsy I had they put tegaderm on over the site. Well Ms sensitive skin herself should of known better than to let them do that to me. I now have a blister the whole outer edge of where the tegaderm was. See if I had gotten enough sleep last night I would of been more alert to these things. So what does one do with a blister like that and has to go to work tomorrow wearing a bra. Mmmmnnn I will have to sleep on this one and hopefully my cousin with the Phd in nursing will email me back a solution.
