How To Remove Large Purple Area On Inner Thigh?

Hi, I m a 19 year old female, I m 5 4 and weigh around 180 lbs.. I am currently in the process of losing weight but I have noticed large purple areas on each inner thigh. They are not sore, there is no pain when I apply pressure, and I ve never really had pain in that area. They just kinda showed up. I m not really sure how long they ve been there, but I m sure a good while now. Should I see a doctor or let it be? I m kind of embaressed by them.. I mean when I get serious with someone will he be weirded out by them? I would also like to know how I can make them go away or at least fade away.. Thank you.
