Rectal Pain

I had my laparoscopic surgery done August 31 and everything was going okay. Until my first period. Now I am two weeks after my period and I am having awful rectal pain. It will only stop if I take Tylenol. I have been taking Tylenol religiously every 4-6 hours for the last 2 weeks. I have told my specialist and they are going to get me in to check Me out. But do you guys think my endo is back? They told me I had stage 2 but removed everything ( I know it can come back but didn’t think this quick!)
