Thank you so much for your response. I am 47. The area on my thigh I just noticed tonight. It was not there for sure a week or so ago. There is no history of having anything like this before, and it is not painful, or pus-filled vesicles like an outbreak seem to be. It is itchy, but not painful. The area on my arm has been a few weeks since I noticed it. It has darkened over that time. I do not have any other health conditions. I am pretty much healthy.
