What are these lumps on my legs?

I’ve had these lumps on my legs for the past two weeks now or something…
They are sometimes so itchy like right now, and when I scratch if feels soooo goood.
I ask my mom she says that maybe it could be tuberculosis, I doubt that is it.
I don’t know what they are.
I have two on my left leg, one under the knee (leg) and one on the ankle. Then again the other leg, but only one.

Help me please cause it’s kinda irritating, it has noting to do with shaving cause I havent shaved in a pretty long time.
