Recently I have found a part of my left thigh that has a small dip. This dip is not visible and when touched feels like the only thing holding me back from going deeper is my skin and not any muscle. Naturally this worry’s me. It is less than 2cm diameter or less than 3/4 of an inch. I only ask what is the reason for this hole as it doesn’t fit the description of other similar ‘holes in thighs’ that I have heard
