Need help - sick geophagus

[fishmommie]

Would appreciate some help. Attached is a video and a still photo of my geophagus, clearly ill.
I've had her since Sept. 7 days ago I noticed I hadn't seen as much of her as usual and she had staked out a spot in a small rock cave. She did come out to eat every day. but I finally got a good look at her and saw 2 pin head sized white spots on her back near her dorsal. Also noticed a larger, milkier spot on her other side near her tail. Same time I noticed her abdomen was swollen.
So I netted her and put her in a hospital tank, did some reading and decided I must be dealing with parasites. She has gone through 2 ick treatments in this 90 gallon in 4 months. I used salt and heat as ick treatment. The heat was well out of her comforzones (per her profile) so I made the decision I was dealing with a stressed induced parasite.
Treated her for the past 7 days with prazi-pro and metro +. did every other day water changes. She has not eaten since I put her in the QT.
The larger spot on her side near her tail is gone. I had thought the other two were gone until today when I put her in a bucket to do a thorough tank cleaning and noticed a larger spot right next to her dorsal. It's milky and looks a bit like a pus sack. About the size of a grain of sand.
Her abdomen is still swollen.

I'm suspecting what I really need are some antibiotics but would really appreciate some of your valued opinions. the only other medications I have on hand are Copper Safe, Pimafix and Melafix.
My regular tank maintenance where she normally lives is weekly 50 - 70% W/C and gravel vac. The tank had been wormed with Prazi and Metro as a precaution a couple months ago. Water Perims: Ammonia - 0, Nitrites - 0, Nitrates - 10 - 15.
I've seen 0 aggression in the tank toward her. She's a sweet, quiet fish, which is probably why I didn't notice she was in trouble sooner and makes me wonder if this hasn't been going on for a long time.

Again, any help is appreciated and if you have more questions I didn't think to address, please let me know.

Notice that in the video I took yesterday, she did not have the larger bump on her dorsal. That seems to have swollen over night.
