Hidradinitis: The most common form of armpit swelling comes from lympn gland involvement either from an infection of nodes or metastasis from chest or arm primaries.

Shingles in aug 2013. Chest, under arm, shoulder. Glands under arm swelled. Feb 2014, slight swelling remains. No pain. Reason for concern?

Yes: As far as shingles, no. You are young and the likelihood of developing post shingles pain is lower (absent any coexisting medical issues). The main concern is why did you develop shingles which tends to occur epwhen your immune system is taxed or is weak. The swollen axillary gland needs to be evaluated and possibly biopsied. See you pcp on monday.

Musculoskeletal: Could be Pressure on the nerves in the area which start in the neck. Burning sensations are a sign of nerve irritation. Could try ice. Careful with advil (ibuprofen) or alleve. They both can irritate the stomach and intestines. Poor posture, over use, sleeping position all could be factors. Stretching exercises may be helpful as well.

I have a swollen lymph node on my under arm, maybe the size of a small grape. I have bad allergies and started my cycle, will that cause the swelling?

Not likely related: Neither your "allergies" or you menses are likely causes of an auxiliary lymph node. Have your pcp assess as to any further evaluation indicated.
