What should you know about onycholysis side of nail?

Separation can start along one side edge and gradually move toward the centre or base. Repeated rubbing from shoes, picking at the nail margin, manicures, water trapped under the edge, and local infection are possible contributors. Nail Fungus and Nail Psoriasis can also affect how a nail grows, but a lifted edge does not establish either diagnosis.

Trim a projecting edge straight across once it is safely long enough, using clean clippers; never dig into the gap. Dry hands and feet thoroughly, change damp socks, and choose shoes with room for the toes. Avoid polish, gel systems, and solvents until the nail settles. Photographing the edge occasionally can help you describe whether the separation is extending. A clinician may recommend treatment after examining the nail and surrounding skin.

Book a review when the side lifting persists, enlarges, or appears on other nails. Get prompt help for tenderness, drainage, foul smell, swelling, warmth, or redness spreading beyond the nail fold. A new dark streak, bleeding without a clear injury, or a nail that changes shape should be assessed rather than covered with polish.

Ask whether friction, infection, or a skin condition best explains the side separation; whether the nail should be tested; and how often it should be checked. If the edge catches repeatedly, ask whether Nail Surgery could help and what recovery care would involve.
