I have a boil, so i applied a belladonna plaster on it to make out the pus but even after two days when i unmatched the plaster the boil had no pus but a little yellowish color appeared in it and it was a little fat and when i squeezed it so that the pus can be made out it did not, but a little amount of blood came out of it and a hole gone made itself on it(on boil) some locals advised me to apply a paan leaf with deshi ghee, i am a little worried, it is on my back, is it a boil with or a normal wound or something else please help me...

It sounds like your boil hasn't fully formed pus yet, which is why squeezing it only caused bleeding and a small hole. Avoid squeezing it further to prevent infection. Applying warm compresses instead can help it drain naturally. If it worsens or doesn't heal, see a doctor for proper care.
