A pus-filled abscess near the fingernail may be caused by paronychia. When the skin surrounding the nail is broken or repeatedly immersed in chemical solutions, bacterial infection can occur, leading to paronychia—characterized by an abscess near the nail, often accompanied by redness, swelling, and pain. When paronychia develops, medication therapy—such as ofloxacin capsules, amoxicillin capsules, or roxithromycin ointment—may be prescribed under a physician’s guidance.
