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.
