See MD : It could be an infection of the lymph node. You should see a doctor for this.

Infection: Sight unseen, of course, this could be hydradenitis, a rather serious infection of the sweat glands in the armpit. It's a worst case scenario, but you should see you doctor tomorrow. You may need antibiotics.
