Rectouterine pouch endo - any info?

[LolaDance13]

Hi folks diagnosed with endo in 2010 and recently pain has returned big time - recently had a private TV and pelvic ultrasound picked up soft tissue indicator of endo in the Left posterlateral serosa and leading into the rectouterine pouch. Left side of uterus indicates scarring or endo also which I knew anyway. Is this serious enough for the NHS gynaecology to consider surgery ? Because this isn’t cancer I’m basically being told my my GP this is a priority and to expect to be on a waiting list just to see a consultant for a minimum of a year xx I’m in agony
