I've been keeping my wife's pearlscale fancy goldfish for close to 2 years now, *her* name is Fido!

So over the past few months she has had an angry red spot on her side just above her right side pectoral fin. It has grown to the size of a pea and is very soft(not a tumor), like a water blister-filled with clear fluid for a few days, that turns red like the top of her head.

This shows the start of the spot- but it is easily 10 times bigger than that now(1/2 the size of a dime)
Ive left it alone, lowed temp, raised temp, added salt, water changed, used Maracyn, laced it, even removed it - everything I could think of, heard might help from here, asked LFS owners...but I'm stumped.
Up until this last week it's just been a growth- now she is sitting on the bottom, not mid tank like she has done all her life...The wife is worried....
She also now does this odd behavior of swimming up to the top-breaching the water then *tumbles* back to the bottom of the tank swimming upside down at times! She has NEVER done this!
I have since removed all but 2 tiny panda cory cats from her tank. I don't think these 2 things are related, but the sitting on the bottom makes me think she has a swim bladder problem....not cool.
The growth is the main concern, but if there are some comments on their experiences and any similar odd behaviors you've experienced will help me try to understand whats up and what I can do to make her better.
Thank you fish-friends!
