How were you diagnosed? Were the sores tested? Were you visually diagnosed?
There is a product called Dermoplast. It's a numbing spray. You can use that on your genitals, and it should help. Make sure you get the one with the blue cap, not the red one, as the red one has antibiotics in it that you don't need. This is what it looks like - https://dermoplast.com/our-products/pain-itch-spray/ It's about $10-13, depending on where you get it, but my can has lasted a long time. I usually end up buying a new one because it's expired and not because I've run out.
You can get it at any drug store - Rite Aid, CVS, Walgreens, etc. When you can, go without underwear and wear loose, comfortable shorts/pants.
You can also use it on bug bites, rashes, etc.
If you start getting a lot of pain, an ice pack also helps, though that's not always convenient.
