Another tail rot identification?

[Cannonball]

Hello all! I have a 10(?) year old beardy that I've had for 2.5 years about. His husbandry is great, it was set up by the previous owner. His tail has always been darker at the end but he's been so agitated lately and I'm wondering if he could be in pain because of tail rot? Like I said, he's an old guy so he's got a few off-looking scales in a couple of different places. Now I'm worried one of them is causing tail rot. I just gave him a bath and put some coconut oil on the areas he's gearing up to shed. Here are the pics

It looks like shed I am going to post some info on tail rot but it is not tail rot

Causes of tail rot are:
1. Injuries/trauma - caused by falls, or by any other bearded dragon.

2. Malnourished - make sure he has a balanced diet and he gets the nourishment he needs

How to identify tail rot:

1. Dried out - Decaying tail won't be able to retain moisture, check if it's dried out completely.
2. Very thin, brittle - Decaying tail won't be able to process nourishment, causing it to become more thin and brittle.
What to do after finding out it has a tail rot:
1. Go to a vet - very recommended

T Ask yourself these questions:
Was the tail recently injured?
Was a part of the tail open (eg wound/scrape/cut)
Was flesh exposed?
Is the tail constantly dark? or does the darkness ever go away (eg when in the tank, different environments)
If you didn't answer yes to basically all of those questions, it's not tail rot.
Tail rot is extremely rare. It's an infection of the flesh, from a wound or injury to the tail.
Tail rot is really kind of just a fancy name for an infected wound, one of which is affecting the tail.ail Rot
