Ingrown nailhttps://en.wikipedia.org/wiki/Ingrown_nail
Ingrown nail is a common nail disorder. It is a painful condition of the paronychium or nail bed. While an ingrown nail can affect the nails of both the hands and the feet, it occurs most often on the big toe. The condition usually begins with a microbial inflammation of the paronychium, followed by a granuloma that traps the nail inside it.

Ingrown nails can be prevented by cutting nails straight across. Footwear that is too small or too narrow can worsen any underlying problem with a toenail.

○ Treatment — OTC drugs
Do not cut the ends of your nails too short. Do not wear shoes that are too tight. Avoid placing excessive weight on your toe while walking.
Use a piece of cotton or a small bit of tissue to lift the nail and separate it from the affected skin.

If you have pain, apply an antibiotic ointment and take OTC pain relievers.

Ingrown toenails are quite common, accounting for about 20% of foot problems in primary care, often affecting the big toe. They're more common in young men, often due to how they care for their nails and the shoes they wear. Simple treatments without surgery include adjusting footwear, managing sweat and nail fungus, and placing cotton or dental floss under the ingrown nail. For mild to moderate cases, options like a cotton nail cast or taping the nail fold might help. Surgery aims to prevent the nail plate from digging into the nail fold, reducing inflammation and recurrence. The most common surgical method involves removing part of the nail plate. Matrixectomy, which prevents recurrence, can be done through surgery, chemicals, or electrosurgery.
