I Have Recently Discovered An Indentation Near My Right Temple,

I have recently discovered an indentation near my right temple, that may be diminishing subcutaneous tissue (surgeon friend suggested), and there seem to be two smaller craters within that space, that could be early chicken pox scars that I never noticed before, because I was younger and the area was more plump.

Now, at 57, I acknowledge my diminishing collagen, etc., but the indent is fairly deep and only on the one side. No pain/headaches, just the sudden realization that my temple was caved in. Should I be concerned?

Thanks,
Angela
