Q: what does it feel like it is painfull or what?
A: Yes, it will hurt. Electrolysis feels like a little bee sting, it kind of has a buzz and electric shock. Or like a static cling shock 10X....ouch! I don't know how else to describe it. Also you will have to go back for repeat treatments, this is not a one time thing. There is a topical cream to dull the pain, Eutectic Mixture of Local Anesthetics. You will have to get a prescription from your doctor.
