I have suspected for a little while that I may suffer from endo, although I've never brought this up with my FS who at the moment is only treating me for PCOS

My mum had to have a hysterectomy at 40 as her period pain was unbearable, and when I was younger (before I went on the pill) I also suffered extruciating pain. I still get pain now, but not as bad as before.

I realise that the only definitive way of diagnosing endo is by lap - but have all of the ladies with endo undergone a lap, or has it been diagnosed any other way?

For those that have had a lap, exactly what is involved?
