The problem where a newly born child is unable to store the milk normally or has a block can be due to Hypertrophic pyloric stenosis
Both these congenital defects need corrective surgery in the infancy and the scar of surgery is the same as you are having.
Once the normalcy is restored there is no long term problems.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
