Endo leg pain!!

Hi everyone , I have just had my endometriosis specialist appointment as I need this before surgery, now to wait for my appointment for laparoscopy during the app I was told I will need a cystoscopy aswell, my surgery is apparently high risk as from my previous surety when I was 2 day’s old the scar is unfortunately inverted and right across abdomen .. hopefully not too long to wait they told me it should be within the next 6 weeks, since last Tuesday I have had really bad leg pain I’ve not banged it / fallen over It Jus cane out of the blue one morning now I walk on it I went to A&E yesterday it was so busy they turned around and said prob siataca and to keep taking my medication that I’m already on , not that does anything for the pain, i did day I’m pretty sure I had a uriine infection, (again) but didn’t bother to check it as it was busy they jus wanted u to be seen and then leave! I have been online and I’m seeing from posts u can get pain with endo!! Is this right? The pain in my abdomen / back leg and groin is Jus so horrific just now .. I’m struggling to get out of bed / work ... thanks 😘
