Depends what kind of lump; maybe it's just a pimple... But if not, see a dermatologist. Maybe it is a keloid or reaction to the metal.

You go and see a qualified medical practitioner (a Doctor) about your problem.
First of all, its "i have a painful lump on the back of my head '''which''' keeps coming back" The lump may be a boil. If it is, try pressing a hot towel to it, using anti-acne medications or soaps,etc, or a doctor could look at it and do a draining or give you medication. If its not a boil, try a anti fungal device shuch a Nizoral shampoo. Or it may be a tumor, in wich case your screwed.
A lump on the back of your head that is itchy may be from an inset bite. If the lump does not go away, visit a doctor.
I believe you mean humpback. It's demise has been brought about by overhunting. Although most nations banned whaling, some still do, and this species is still coming back.

A smelly lump on the back of the head may be an infected abscess. It could also be a sebaceous cyst.

A lump on the back of the head could be a simple knot from hitting your head on something like a cabinet. It could also be a cyst. A doctor is the only person who can diagnose the lump.
It is probably a mat. Take hair scissors and carefullycut it off. If you mean it won't go away as in it keeps coming back, you probably need to brush your cat's fur. If it isn't made of fur or something else weird like a bump beneath the skin, it could be very serious and you need to take your cat to the vet right away.
