Lump at top of vagina

Hi all, I'm new on here.

I have an extensive medical history with gynae. 

I've been suffering with pain where my ovaries were (had hysterectomy in 2016, ovary & cyst removed 2017, other ovary & cyst removed 2018. I initially asked for everything to be removed but wasn't listened to)

I had an ultrasound scan over my pelvic area and an internal scan whiched showed up a white lump at the top of my vagina/cervix area. Now since having the scan last week the pain has gotten worse, constant. Continuous pain. Also a dull ache in my lower back and top of my leg (same side) 

I have been wondering whether to go to a&e but I don't want to burden them and I have a family to look after and don't want them to worry.

Has anyone else been through anything similar?

Thanks
