Could be. Have a full STD screen for a proper diagnosis.
It seems worth getting tested to be sure, so then if it is anything you can get treatment.
However, I wonder if it could also just be irritated skin causing the soreness and burning. I’ve had extreme itching, discharge and pain from too much friction during intercourse a few times.
Are you sure that those white bumps were never there, or you just never happened to notice them? Wondering if they’re just part of your normal, but that you’re noticing since you’ve been having the other issues and paying closer attention.
Either way, a test is a good idea to make sure, and if it’s not any kind of infection, you can get peace of mind and figure out what else it could be and go from there.
Good luck.
