Are we talking about a mole (a pigmented thing which tends to stay the same size unless it becomes malignant, a melanoma) a wart (viral, contagious, can grow and spread), a verucca (viral wart, usually on weight-bearing part of foot, so grows down into the skin, or something else?
I don't know cos I've not seen it or felt it.
Anyway, I'm not much of a dermatologist.
I think you should see a doctor, who can give appropriate advice.
Septicaemia is bacteria multiplying in the blood stream so you won't get septicaemia in your mole unless you get it in the whole body, which is unlikely.
Get some decent advice from a qualified person who can look at and feel your mole.
