To confirm if you have a lump, gently feel the area with the flats of your fingers, noting its size, texture, and whether it hurts or moves. However, only a healthcare professional can accurately diagnose a lump. You should not take any medication without a doctor?s evaluation. Lumps have many different causes, ranging from harmless cysts and infections to benign or malignant tumours, and the correct treatment depends entirely on the diagnosis. Taking inappropriate medicine can be ineffective or harmful. Please schedule an appointment with a doctor immediately for a physical exam and any necessary imaging (like an ultrasound) to get an accurate diagnosis and safe treatment plan.

A painful, inflamed armpit lump is often a boil, blocked sweat gland, or swollen lymph node. Avoid squeezing or popping it, as this can spread infection. For relief, apply a warm compress for 10-15 minutes, 3-4 times daily, and take over-the-counter pain relievers like ibuprofen. You can apply a topical antibiotic ointment (such as Bacitracin), but this will not reach deep infections. Because armpit lumps require proper evaluation, please see a doctor. You may need prescription oral antibiotics or a minor drainage procedure. Seek immediate care if you develop a fever or if the redness spreads rapidly.
