A Verucca is the name for a plantar wart (wart on the foot).
it culd be the beginning of a plantar wart also
You can also use neem soap and put tea tree oil on the nail and itchy skin, but try to put the tea tree oil on once or twice a day for a month.
Itching and peeling underneath the toes or in between the toes, usually is Athletes foot. This is a fungal infection, that is usualy caught walking bare footed where someone else with althletes foot has trod. For example in showers in the swimming pool, or trying on shoes that some one with althletes foot has tried on.
You can get creams and powders for althletes foot from your pharmacist or a superstore.
It is important to keep the feet clean and dry in between the toes. The fungus likes warm and moist conditions. Use cotton socks instead of manmade fibre socks.
If you have picked up a Verucca (a wart on the foot) again from walking barefooted where someone else has been that has a verucca. Veruccas will sometimes come up like a calus (hard skin) and then will get little white or black specks, the roots grow inwards.
I suggest you first treat your foot for Athletes Foot and use the creams and powder for this.
