When to See a Doctor

Seek professional care if you experience any of the following symptoms

Possible Causes

  • Ingrown toenail

    A condition where the corner of a toenail curves and grows into the skin, causing pain and swelling. Risk factors include obesity, small-sized shoes and cutting the nails wrongly.

  • Alopecia areata

    An autoimmune disease where the body's immune system attacks its own hair roots. This causes areas of hair loss which are usually patchy and round in shape.

  • Candidiasis (oral, hands and feet)

    Normal human skin contains bacteria and fungi. Candidiasis happens when the fungus overgrows and invades the skin. Risk factors include warm moist environments, and a weakened immune system.

  • Psoriasis (except for pustular psoriasis)
  • Pityriasis rubra pilaris

  • Lichen planus (including nails)
  • Spoon nails (koilonychia)
