Okay..here's a photo I took of Mister's comb today.
This is the side I normally see. Just discolored at the top:

But when I went out to take photos and saw the other side I see that he has a blister:

I have not done anything to it at this point. I am observing and if I see any weeping or any change I'll decide what to do at that point. Had a bit of a conversation with Aoxa and Sally8 about it. Aoxa has some pretty low temps up there so I wanted to hear her thoughts.
