Thanks for the detailed history shared .
I would recommend you to consult a general surgeon , and take advise from him . Most probably this will be a sebaceous cyst , which is actually an infected sweat gland ( skin appendage). This non cancerous swelling is the most common cause of infected swelling in underarm area .
Please get back to me if you have any other symptoms or difficulties other than mentioned above . You can consult if you wish so . Thanks
