STD question (please no hate)

J
I've had chlamedia before, no big deal- got rid of it. Well I got it again from this cheating nasty jerk and well I had a C section 5 months ago. I know that the virus attacks your uterus... And some women get very light to mild pain in their uterus if they get any symptoms at all. 
Well my uterus... Feels like someone took their fist and was trying to yank it out. Not on my period... But could it be because I still Have scar tissue and makes it Worse? I honestly can't can move when it starts hurting. I have to pause and freeze in that position, because it's so painful. 
Any thoughts or advice?
