9. Overgrown nails:
Overgrown thickened nails are a common consequence of fungal infection. Moreover, they also form a symptom of reactive arthritis and psoriasis. A condition known as ‘onychogryphosis’, in which the toe nails grow excessively long and resemble a ram-horn, must not be confused with the thickened nail occurring due to fungal infection. The latter mentioned scenario is of common occurrence in the old age group, in whom the nail overgrows as a response to long-term pressure.
