Wrist wasting

I have been wearing my watch consistently for a few months. Now I notice that my wrist, directly under the watch is wasting. I have also seen others comment the same, yet no response from Apple?

I do not wear it tight, it is relatively loose, so it’s not simply an indent from the pressure of it sitting tight to my wrist. I’ve taken it off for 36 hours now, yet the intention, with noticeable lack of tissue remains. It is visibly indented and looks different from my other wrist.

Please advise.
