Painful lump in armpit
I developed a pea-sized lump in my right armpit on Thursday. It feels deep under the skin, is hard, fixed, and tender. The skin over it is intact with no redness, pus, or drainage, and the swelling has remained about the same size.
I started my period today and I usually get mild breast tenderness before my periods, but this is the first time I’ve had an armpit lump. I shaved my armpit about two weeks ago. I have started applying mupirocin ointment and warm compresses.
Could this be an inflamed hair follicle, boil, cyst, reactive lymph node, or something related to hormonal changes? Does this presentation raise concern for breast cancer, or is that less likely given the sudden onset and tenderness?

Based on your description, the most likely possibilities are an inflamed hair follicle/early furuncle, a small inflamed epidermoid cyst, or a reactive axillary lymph node.
Next Steps
Continue warm compresses for 10–15 minutes, 3–4 times daily, avoid shaving or squeezing the area, and maintain good hygiene. Mupirocin may help only if there is a superficial bacterial folliculitis; it is less useful for a deep lymph node or cyst. Start on oral antibiotics after consultation

Sudden onset and pain are typical hallmarks of an acute inflammatory process—like an infection or a reacting immune system—rather than a malignant tumor. Cancerous lumps in the breast or armpit usually develop very slowly over months and are typically completely painless. While a doctor must always evaluate a new lump to be 100% sure, its sudden and painful nature makes breast cancer much less likely.
Next Steps
Keep up the warm compresses
Health Tips
If the lump rapidly grows, if you develop a fever, or if the skin over it becomes very red and hot to the touch, you should be seen by a doctor right away.

This presentation is much more consistent with a reactive lymph node than anything sinister. A tender, recently appeared armpit lump coinciding with your period onset is very typical â axillary lymph nodes commonly swell in response to hormonal changes around menstruation. The history of shaving 2 weeks ago could also have caused a minor follicular irritation that triggered a local lymph node reaction. Breast cancer lymph nodes are typically non-tender, slow-growing, and not hormonally linked â this pattern is reassuring against that.
Next Steps
Continue the warm compresses. Monitor over the next 1-2 weeks â a reactive node usually resolves on its own after the period ends. If the lump persists beyond 3-4 weeks, grows larger, becomes non-tender, or new lumps appear, see a doctor for clinical examination. Please consult me directly on Practo for a detailed evaluation.

The difficulty you have put forth looks more like an infected lymph node
Take an anti inflammatory tab and an antibiotic for a period of 5 days and you should do well
However do consult your general ohysician snd get his opinion too
In case the whole thing does not subside in about t days ... further investigation may be necessary

The sudden onset of a small, tender axillary lump in a 25-year-old is more suggestive of a reactive lymph node or an inflamed hair follicle/sebaceous cyst than breast cancer. Continue warm compresses and avoid squeezing the swelling. If it persists beyond 2-3 weeks, enlarges, or is associated with a breast lump or fever, consult a Surgeon for examination and an ultrasound of the axilla. The current presentation is reassuring but should be followed up if it does not resolve.

If the swelling is painful, it may be due to a boil or an inflammatory/infectious process. Please consult a doctor for a proper examination before starting any antibiotics, as the appropriate treatment depends on the underlying cause. Seek medical evaluation for further diagnosis and management. If you develop fever, increasing redness, rapid swelling, or severe pain, seek medical attention promptly.
