[Breast Enlargement] Side effect of breast surgery: loss of sensation on one side of the chest

The part circled like that is really painful, no matter how much I pinch it or stab it with a sharp object, I can't feel anything. I went to the hospital several times, but they came back and said let's wait a little longer. At first, they said let's wait a year, but then they went again, let's wait even more, let's wait, and so on. It's been 2 years of wasting time... How should I be compensated for this... Hospital hint: 'Very good'
