Girls help

So I've been having really bad pain during sex since last November so it encouraged me to get tested for absolutely everything to rule things out. I got tested for any natural problems as well as STI's. I tested positive for chlamydia and thrush and both were treated. What worries me is I was clear of everything before being with my partner for a year and it's obviously come from him. The pain still hasn't gone but I know that everything is treated now, the pain is a burning sensation and I feel like I can't relax and I can't carry on having sex with my partner. Has anyone had this issue?
