Got all clear for one breast but worried about other

I attended breast clinic on Tuesday for the purple/pink mark and swollen breast and thankfully all clear from ultrasound scan and Consultant said it wasn't 'angry' lol love that term.

But got out of the shower just now and noticed a dent underneath my breast when lifted up my left arm and breast when looked in the mirror.

I feel like an over worrier as this is a new to me and don't want to waste more time when there are others that need it too.

Does anyone else feel like this?
