Hello, I can understand your concern for pronounced nodule on your cheek. I can get form your history that you got injury on your cheek after fallen down on ground. It is quite a common phenomenon that during an injury one can get dust particle or any stone or any foreign body entered into the skin. This causes the typical phenomenon called a “foreign body Granuloma” and gives the appearance of a nodule at the affected site. I suggest you to meet a surgeon or a dermatologist where a through analysis of the area can be done to check the area properly. In my patients I usually prefer to explore the area and clean the area to remove the stone or any foreign particle from the nodule. A course of oral antibiotic such as cefixime or ciprofloxacin reduces the chances of infection. All the best.
