Might be able to. Can't speak for experience of a Dr.
Will the doctor be able to tell if is a chancre by looking at it?
Not sure what you are asking
Thanks for the reply. But if I talk to my doctor about it will he not be able to see whether it really is a chancre?
Well testing now will not tell you anything. The canker normally starts at about 3 weeks. Testing is valid at 6 weeks.
Also test for HIV at 3 months and USE CONDOMS!
