In brief: Lump under the arm

The under arm lump can be an infection, caused by shaving or a bad bacteria, like staph aureus.
It could also be something worse, like a tumor, and in either case, your mother should see a doctor for a proper diagnosis and treatment, especially if it is making her arm numb.

In brief: Possibilities

There are a number of possibilities; it could be an abscess, an infected lymph node, or a tumor pressing on something.
She needs to see her dr & have it checked.
