Is it normal to have indents in my thighs

Okay, so yesterday I noticed this indent going horrizontally across my left thigh a little further up from the very center of my thigh. There is also one on my right thigh but it's smaller. Also, my left thigh hurts like cramping and so does my back. I walk up and down stairs all day and I have a pinched nerve in my left shoulder that(i beleive)is almost healed.
