Female clownfish has raised red mark on her side

[An_Enemy]

My female clownfish has raised red mark on her side. It's a raised red area that's pushing up under her scales. Wasn't there yesterday, it's sudden and looks pretty bad.
Anyone know what it could be or have advice for treatments?
I have methylene blue, API General Cure and Seachem Focus

Hard to lock down with pics but appears to be at one point a scrape injury but may also be an infection. Likely it is what we refer to as clown bruising which is typically visible on white areas of the body and appears as uronema but is not. Its not contagious and seems to affect mainly captive bred species.
You can treat witrh reef safe ruby rally pro however at times treatment not needed and fish often improves or declines

I'm not a disease expert, but it may be Bruising Disease:

Clownfish bruising/lesion?

All, Over the past two years or so, I've come across dozens of cases on the fish disease forum here of an issue with clownfish that we have not been able to identify. I've never seen it on any clownfish I've had myself, but the issue seems most common on designer clowns, which I don't work...

Looking through the bruising thread, seems like some do fine and others don't. More of a symptom than a cause, it looks like.

I've giving her a 30 minute bath in a jar with methylene blue for bacterial infections and seachem focus for parasites just to be safe.
Considering how it appeared overnight and she prefers to sleep at the bottom of the tank, I'm hoping it's just a bad bristleworm sting. Her behaviour doesn't seem any different and her appetite is fine.
Only creatures I've bought in the past five years have been inverts, so hopefully that means a low chance of disease/parasites.

Updating if anyone finds this thread useful down the line. I've scheduled a vet visit, but they won't be here until next week. The swelling has gone down, but the 'bruise' is still there. No changes in behaviour or appetite.

An update for anyone wondering, vet wasn't able to visit until yesterday, but the clownfish is in good health. No parasites or illness, the vet's guess is that she scraped herself on a rock. The medicines wouldn't have helped, but the methylene blue baths would have helped. The wound has mostly healed at this point.
