Possible "rash" upper inner thigh?

mama.jinx • Wife // mama // coffee snob // Gemini
For a few months or so, I've had this "rash" for lack of better words on my upper inner thighs. Like almost touching my stuff, but not quite. 
It's small spots of reddish pink, several in small clusters. But it does not itch, at all. Ever. it's kind of raised a little. 
About a year ago I saw something there verrrrry faint but it went away. Now it's there and won't go away. It doesn't itch but I'm still worried. Especially with my moms problems with cancer in that area. I'm only 20 though. Maybe I'm paranoid. But does anyone have any idea? I've googled every thing I can. 
Not eczema, not an std, not chaffing or friction because it doesn't hurt, could possibly be Pityriasis Rosea?But when looking that up, mine spots don't have a big one and a small one. 
Didn't know if anyone here has had a similar issue or is in the medical field or what. Since my mom has been sick I've missed a lot of work so I wanna know possibilities before having to miss more to go to the doctor if I even need to
