Without: Without examining you, it's difficult to say exactly what it is.

There are many common things that a hard, red lump in the armpit skin could be such as:
- inflammed lymph node
- ingrown hair
- sebaceous cyst
- abscess or boil (infection)
- folliculitis (infection of the hair follicle)

if it is painful, enlarging, or if you are suddenly noticing more, give your doctor a call. You should start with your pcp first since they treat a wide variety of problems and you are more likely to be able to see them sooner than a gynecologist or dermatologist. Odds are, they'll be able to treat you. If they think you should see a specialist, they'll let you know. ...Read more

I have a lump under each armpit. One has gotten smaller and the other just showed up. They are painful to touch. They are small pea sized lumps and hard?

I'd Bet It's Sweat: May be small areas of infection. Sweat glands can get irritated or clogged then get bigger & painful.

The topical antibacterial gels with aloe work well but if you sweat a lot you may need something milder. ...Read more

It does not become obvious for some women until they begin to lactate, at which point the tissue produces milk but cannot drain effectively. This area can be iced and compressed and hopefully the tissue will stop producing milk and will shrink, without affecting her milk supply for the baby. Try to avoid stimulating the area. ...Read more

Doctor can check: One's doctor can carefully examine the breasts and armpits to see it they feel normal. Breasts normally extend towards the armpits, but if a woman has swelling in her armpit area each time she has a baby and breastfeeds, she might have some extra breast tissue (milk-producing glands) in the armpit area. That would be an "extra" breast, a small lump without an extra nipple. ...Read more

Another possibility is Hidradenitis suppurativa, but your Dermatologist will be the best person to help you with this problem. ...Read more
