Welcome to Healthcare Magic Forum
From your description, it looks like you have developed viral warts
Such lesions usually start with a single lesion, and if adequate treatment is
not done in the initial stages, then it tends to spread very quickly and that is
what has happened in your case.
There are various treatment options for treating such lesions.
Chemical cautery, electric cautery, Radiofrequency ablation
are the most
commonly used methods..
These lesions are contagious too, so it would recommend that you should visit a skin
specialist soon to get these lesions removed.
Hope it helps
