Probably not. See a Dr for an exam.
Could this still be an STD?
Syphilis presents with 1 canker not several.
I have just noticed that another one of these marks has increased inside. The original marks/sores habe seemingly started to scab but the newer border around them is still fresh skin. I have also noticed that the amount of marks/sores have increased in size. If someone could please tell me what this might be it would be appreciated. I'm a 19 year old female if that helps
