soft holes / divots under skin on legs

I have a few divots in my legs under the skin.  There is not pain or too much feeling.  It's as if my skin is detached from the flesh in that spot.  The holes aren't large and they're not exactly small either, maybe the size of dime or nickle.  I have two on my left ankle, one on my upper outer thigh, one on the upper inner thigh of both legs, two on my bottom and one on my lower back above my bottom.  At first, when I first notice them, I thought they were the beginning of out of shape stretch marks.  I also, thought that they were in the process of becoming some sort of mole.  I have no idea as to what it could be.  I want to have some sort of inkling so I can tell the doctor as to what "I" think it could be.  Because so far, my family doctor just dismisses it.
