Hi Dear,
Welcome to HCM.
Smoking does not cause boils or furunculosis or carbuncles, though it does harm your body in many other ways, most serious being
lung cancer.
These boils need to be treated with
oral antibiotics and local
antiseptic lotions or ointments, otherwise they will spread from one area to other. Consult a doctor immediately and yes
quit smoking before it's too late.
Wish you speedy recovery.
