I'd appreciate some help! I'm not sure if my turtle of almost 20 years is sick... It was drying off on his rock when I noticed a white lump from its hind leg. The flesh near the shell was unusually light and had a pink tinge. It's been a few days and it doesn't look like the pink tinge has gone away, and its flesh is still bulging out. It almost looks swollen. According to my brother, it looks normal but this is the first time I've noticed it and I check on my turtle quite often. I also started noticing that my turtle was shedding its skin. Not excessively, though. I only noticed it around the neck but today I saw that one of its front legs was visibly shedding. But it's just barely visible. I'm afraid this is a sign of infection. I've been looking for info on these symptoms on the internet but can't confirm whether these are bad signs.

He also has abrasions to the bottom of its shell...mostly minor, nothing irritated or bleeding. However there is a small cut that's been on the shell for a while. It's faint red but looked like it healed since the layer of shell seemed to be growing back...last I checked it seemed to be getting more pink but I'll need to check again. I'm mostly not home on weekdays.
I admit my turtle isn't living in the ideal habitat.
Now for the questions:

Are you using a water conditioner? - ???
Are you using any filtration? - yes, Tetra filter
What is the basking temperature? - n/a

Have you searched the forums for similar situations? yes, i've seen similar cases but don't know the outcomes...
Is there any other unusual activity/symptoms? - not really...my turtle did crawl on a door mat once and twisted around like it was itchy
