I'm in the uk and have a sabacous cyst in a private place. nhs refuses to treat because it's cosmetic. what can i say to get them to treat me?

Painful or bleeding?: Is it painful or bleeding? Does it seem infected, draining pus? Does it interfere with urination or sexual intercourse? Is it rapidly growing which might be a sign that it might not be a cyst but a tumor or cancer.

It is a pathology: Sebaceous cysts are accumulations of skin oil due to failure of ducts to get it to the outside skin. Body reacts as if a foreign material and walls it off with fibrous tissue forming a pseudocyst. This requires opening and drainage, to include the gland tissue causing it. May become infected and require bigger surgery. Not cosmetic.

If it is infected: If it is large and infected, you should not have any problem getting treated.But, if it is small and asymptomatic you may have to do lot of explaining.
