Thank you for your response. I read the information on the link you provided, but it refers to light brown, blueish or dark patches while mine seems to be a "discoloration". I took a picture under a black light to help you confirm or change the diagnosis. let me know what you think.
Thank you, Carl
Thank you Dr Attili,
You confirmed what I suspected. Not having a family history to support a genetic cause, I believe stress can be the culprit. Are there any other reasons this could have started?
I already ordered both medicines and will post in 8 wks or as soon as I see any change in the condition.
