I woke up this morning to find Chanel sick

This is my first sick fish so I have no idea what is going on. Yesterday morning I did a 100% water change ( i try to do them every 2-3 days as she is in a smaller tank), and she was absolutely fine (no fuzz, no bump on her spine or clamped fins). I usually check on all my fish before bed too, and she was fine last night. Overnight she seems to have developed strings of fuzz hanging off her, over her eyes (the best I can describe it is that it looks like skin or something hanging off, kind of like when a snake sheds it's skin), clamped fins, and a strange bump in her spine. Please help :( I really hope I caught this early enough so i can treat her.

Random skin type stuff over her eyes and fuzzy lines coming off of her.

You can really see the little bump/hump on her in this picture. I tried to circle the fuzz on her, sorry if it's hard to see.
