Odd mark on my beardies lip.

I posted this else where to.. But figured id try here as well..

I have a 4 month old juvenile bearded dragon. Im a new owner. I have had her for a little over a week.
She has proper set up with everything i have read.
Her encloser is a 50 gallon tank.
UVB is a reptisun 10 thats about 8 inches up from lowest point.
Her basking light is a 100 watt mercury vapor bulb that's 12 inches above ger basking spot.
Basking heat is 100 to 110 depending where she basks on her rock.
Cool side is 80 to 90 degrees.
She basks a normal beardie would seem to.
Offered a mixed variety of greens daily as a salad.
She eats well.
10 to 15 - 1/2 inch crickets. Gut loaded with greens/veggies/fruits.
Eats 2 to 3 times a day.
Gets her calcium with D3 every other day. Don't know if it should be daily.
She's quite the active girl. Unless basking.
Loves being held and likes to explore.
She's bathed about every other day or two.
Since she doesn't really like drinking from her dish.
Which from my reading on here seems normal.
I'd attach a picture of her lip. But i dont know how via a cell phone.

Also just noticed this on her tail. Accidentally touch it and she winced a little.

Hello,

Is it swollen? How big?
Wash her tail and see if it’s just powder ( I don’t know what it is, just trying to narrow it down)

Is it tail rot? My baby lost a bit of her tail to tail rot.

Is it shed? If it’s pale, flakey, and dry it’s probably shed. If it’s stuck mist her. It appears to be shed.
If you don’t have a mister giver her a warm bath for 15-30 minutes

Nah nothing seems swollen ger tail is pretty symmetrical all the way down. I tried soaking here and wahing it off yesterday. Nothing. I mean i accidentally put pressure on her tail and her tail winced a little.
Don't think it's tail rot.. Cause that is the only spot like that at current and the tip of her tail isnt black.
I mean some of the coloring of her scales is a dark color going down her tail like on the edge of protruding scale on the brown areas of her tail.. But not like that spot.
And i have had her for a little over a week. So im still pretty new. But other than that she eats well and is really active. Well minus when she's actually deciding to bask and then wants out and to get attention. Lol. She likes attention. And she seems pretty healthy to me.

I don’t think it’s something to worry about. I said the shed thing because my bearded dragon goes through sheds 2-1 a year. She has a hard time shedding.

The bump on the lip is probably ok. If it grows,swells, oozes or anything unordinary then I’d consider the vet. I hope she/he’s ok.

I mean the shedding may make sense she is 4 months old. Amd her back feet seem some what dried out sometimes. Amd her tail from the base. Dont quite match the tone as the rest of her.. Its hard to explain. Seems not as.. Stand out color wise. And there seems to be a line that isnt even around her tail that seems semi dry or something like that?? Like i said hard to explain.
