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.

Since you fell from a height, please have a doctor evaluate you immediately to rule out a concussion or head injury. For the wound, gently clean the area with mild soap and water. You can apply a thin layer of a generic antibiotic ointment, such as bacitracin or polymyxin B, and cover it with a sterile bandage. Because diabetes can slow healing and increase infection risks, keeping your blood sugar well-controlled and having a professional check the wound is very important. Avoid using rubbing alcohol or hydrogen peroxide, as they can damage tissue and delay healing.
