It doesn't sound like an STD. I recommend seeing a dermatologist when the spot is present. I suspect the lightheadedness is unrelated. Neither problem sounds serious.

Thank you for replying. I forgot to add that I also have a funny taste in my mouth. It has been like this since the symptoms started. The feeling is like having a metallic taste all the time.
BTW, thank you for the work that you do in the forums.
Still doesn't sound like an STD, but see a health care provider if the peculiar taste continues. Doesn't sound serious, but it doesn't ring any bells in my mind.
Thank you for the kind comment. You're welcome.
