Onycholysis is a condition that occurs when a fingernail or toenail separates from the pink skin on the nail bed. It's usually preceded by a gradual separation that may or may not be noticeable because it typically is not associated with extensive pain. Traumatic injury is the most common cause of onycholysis, according to the Aetna Intelihealth website, although nail fungus contributes to a vast number of cases as well. Treatment for a lifted toenail varies depending on the cause.
See your doctor for a definitive diagnosis so that you can treat the underlying disease causing the irritable condition on your toes. Various diseases that can cause onycholysis include hyperthyroidism, diabetes and psoriasis. A fungal infection requires different medication to begin the healing process. Other conditions that can cause toenail lifting include overexposure to ultraviolet light, herpes and medication interactions.
Keep your toenail dry. After a bath or shower, take time to thoroughly dry all sides of your toe by patting gently and holding the towel over the exposed skin to soak up excess moisture. Wait to don socks or shoes until the surface is thoroughly dry.
Trim your nails closely to remove the ends of the toenails that have begun to separate. Use sterile, sharp clippers or scissors. You often can prevent losing the entire nail by cutting it as close as possible to prevent the loose nail portion from catching on a sock or tight shoes.
Wear shoes that give your toenail plenty of room to breathe and that don't restrict the nail bed or irritate any part of the loose nail. Shoes that pinch or squeeze the affected toes can cause additional complications and impede the healing process.
