How do you know when an OB has finished?

My first ever OB was around 16/12/20 and I was swabbed and diagnosed with HSV-2 on 21/12/20. There are no longer ulcers or pain but what looks like red scars and sometimes I might get a tingle/itch or discomfort. How do I know when my OB is fully gone? Also has anyone noticed a change in the appearance of their 🐱 since their first OB? I feel like mine looks a complete mess compared to before 😣
