Slight dent in breast

Hi,

I recently had an appointment at the breast clinic after find a small lump in my orght breast. I had an ultrasound and thankfully was told everything is okay. However I noticed on the same breast there is a very slight dent whenevr I lift my arm. 

Im not sure if Im overreacting as it is very faint and not noticable. Im 19 years old and also suffer with anxiety so you can imagine how much Ive been panicking about this!

Has anyone experienced anything like this which turned out to be nothung? Im just reasurring myself its all oay as I only recently had an ultrasound so I imagine if anything was wrong it would have been sound in that scan?

 

Thank you if you've read this far xx
