Breast reduction?

[Itsmeaga1n]

What are the criteria for a breast reduction on the nhs?

I'm 5 feet 7 and need to lose 2 stone. However my bra size is 34/36 gg/h. I hate the way they look and they are painful and heavy. I've been thinking about a breast reduction although haven't looked into it in detail yet, but there is no way I'll be able to save enough as something keeps coming up that takes away any money I may cobble together.

What are the criteria for a breast reduction? Anyone had this and can tell me a little about cost of going private, surgery time, recovery time, pain etc?
