Ok so I won't explain my story because I posted on here many times about the cyst above my chin that won't go away even after a cortisone injection. It's actually a living nightmare for me. It's all I think about even though I am trying not to. 2 months to have 2 of these things on each end of my chin is just ridiculous. I'm on accutane and have an appointment with the dermatologist again on Monday and I just wanted to know how do they know how much cortisone to put in to a) make it go away for good and b) not cause an indent.

Is this something I should go to Toronto for to ensure that it gets done properly? Or is this just something that even the best dermatologist can't promise?

Thanks in advance.
