I understand, although there is no question that these symptoms are indeed due to an STD. Again the question is which one? As you note, the only way to know for sure is to get tested, given that it is impossible to offer a diagnosis via the internet. I just figured that you would be able to narrow the 'candidates' so to speak, or perhaps suggest a likely disease that you knew to be consistent with the aforementioned symptoms. Thank you nonetheless.
Re-read my closing comment above "But even then, no online expert can make a definite diagnosis. No matter what else happens, he needs personal health care to get the answers." Anyway, once it is clear a problem isn't due to STD, this forum doesn't go any farther.
I won't have any more comments.
Sure, what other details could I provide?
If you're not actually talking about yourself, it would be best if your "confidant" posed the questions. It's hard enough to be sure of accurate descriptions when people tell their own stories.
The word "chancre" means a syphilitic lesion, but that's probalby not what you mean. No STD is likely to cause such a problem, although conceivably it could be herpes--but impossible to guess further without more detailed description.
As for the other symptoms, no STD typically causes such symptoms. "Small bumps" conceivably could be warts, but as for the thigh lesion, more detail is required to speculate.
No STD causes odor. The only exception is bacterial vaginosis (not actually an STD) and trichomoniasis in women, but in those cases the issue isn't the sexually transmitted nature of the problem, but has to do with normal bacteria growing to abnormal levels in the vagina.
Your "friend" needs to see a health care provider. If he wants to come on line and add more detail about some of his symptoms, we might be able to make a somewhat more educated guess. But even then, no online expert can make a definite diagnosis. No matter what else happens, he needs personal health care to get the answers.
