It seems that the growth on great toe you suggest ,would be a wart.
Also called verruca
caused by virus.
It is contagious disease, that is why it should be treated as early as possible.
Treatment is very easy and simple.
Electrocautery under local anaesthesia may be done by expert., It is a simple OPD procedure .Cryotherapy
and laser ablation
are other methods.
Chemical cautery using TCA is also used to cure wart.
Anyways, consult dermatologist
, discuss with him and go ahead for treatment.
I hope you got my answer.
