Thanks for your question on Healthcare Magic.
I can understand your concern.
That incidence might have injured the
soft tissue of nipple and
areola. This injury heals by
fibrosis which gives hard feeling underneath your nipple.
No need to worry for this hard disc like feeling.
This can not cause heaviness in chest.
So for your heaviness feeling, we should rule out heart diseases because you gained weight also.
So get done ecg and 2d echo.
If both these are normal then no need to worry for heart diseases.
Sometimes, simple
stress and
anxiety can also cause similar heaviness in chest.
So avoid stress and tension, be relax and calm. Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
