Hello and welcome to Chat Doctor, Lump under the arm associated with pins and needle sensation in the arm and hands suggests nerve related disorder. Pins and needles sensation is can be due to compression of the nerve supplying the arm and hands or the lump can be arising from the nerve itself. Thus, I suggest you to consult your primary healthcare provider for clinical assessment of the lump. You may need to consult an orthopedic to assess the nerve supply of the upper limb. Thanks and take care Chat Doctor.
