I accidentally burned my post-mastectomy implant two weeks ago. Not sure if it's healing okay. (Photo)

Two weeks ago, I left a heating pad on my post-mastectomy breast. It burned and there was a big blister. They removed the blister in the ER, and it was looking better. I applied silver something ointment twice a day for over a week and kept gauze on it. First picture is how it looked right away. Two weeks later it's caked in hard blood. I'm not sure if it's healing, if I should keep treating it, etc. it kind of looks worse. That's the second picture.
