This most likely sounds like a furuncle (boil) / infected hair follicle in the underarm. Due to sweat, friction, and hair follicles in that area, these are quite common.
Next Steps:
• Start warm compress (10–15 mins, 3–4 times/day) → helps it drain naturally
• Apply a topical antibiotic (like mupirocin or fusidic acid) 2–3 times daily
• Take a pain reliever (paracetamol/ibuprofen if needed)
• Keep the area clean and dry
• If swelling increases or pus forms → may need oral antibiotics or drainage by doctor
Helpful Tips / Word of Caution:
• Do NOT squeeze or pop → can worsen infection
• Avoid shaving/waxing till it heals
• Wear loose cotton clothes to reduce friction
• Maintain hygiene and avoid deodorants temporarily
When to see a doctor urgently:
• Fever or rapidly increasing pain/swelling
• Redness spreading
• Not improving in 3–5 days
• Recurrent episodes
