my bun's tail has a small hard lump of sort

[Happy Hopping]

so about 1/3 of the length of her tail, in other words, literally near the end of the tail, I discover a 2mm diameter circular hard lump. For a human, it would be say a cyst for e.g.

It can't be a mosquito bite, as it doesn't feel soft. Just as of the past 2 weeks, she was outside for 20 to 30 min. per day, as the weather gets quite warm. But even if it was some sort of insect bite from some insect at the backyard, in which so close to the end of the tail, I suppose an insect can access to, can it be hard lump like that?

I have an exotic pet trimmer, I can trim that part of the fur and see what is going on

what else could it be?

I think the only way to get a definitive answer is to let a vet take a look at it.

in the end, the vet said there is nothing needed to be done, he thinks it's a previous fight from the 2 buns
