Dermatology Questions? Ask an Online Dermatologist.
Hi and thanks for the query,
It seems like these are inflammation of glands specially in your armpit, they can be from scratching dry skin or from infection in the lymph nodes. I would suggest you should get them examined by a physician as any lump in the axilla is to be evaluated thoroughly to rule out any breast disease. You should apply good moisturizer if the area is dry but you might need steroid cream in case of dermatitis or antibiotics depending upon physical examination. Take lots of fluid to keep your skin well hydrated.
Let me know if you have further questions.
Wish you good health.
