  4. 4.Chronic Nail Infection (Paronychia)

    Chronic Fingernail Infection (Paronychia) is caused by repeated damage to the cuticle (the thin layer of skin that covers the base of the nail). The cuticle protects the nail from infection, and when it's damaged again-and-again, it can predispose someone to infections of the nail (paronychia).

    Really depends on you - the more you are protecting your nails, the more likely you will heal

    Rarity:
    Rare
    Top Symptoms:
    spontaneous finger pain, fingernail pain, cuticle loss, fingernail swelling
