Hi, My name is Terri Martin. I have a couple of questions that I would like to ask you. 1). I m a diabetic and have Type 2 and I take Metformin, I just read on the internet that it could be harmful, is that true. 2), I also have this pain in my left breast and it is very painful(tender to the touch), and I was prescribe Bactrim, is that a safe drug to take?
