That is horrible. They should have sent a letter and told you back in January who was taking over your care. Call patient relations first, 617-632-3417, then call the President's office, 617-632-4266, if you don't get an appointment immediately, third is go to the ER if there is an open sore. I, personally, would consider the ER first if there is an open sore. That gets you assigned to a doctor quickest.
I got these numbers off of their website and I have not been there. I hope this helps.
