Pyloric ulcer repair @ 3 days old. What can be done to fix this scar? (Photo)

I had an ulcer repaired at 3 days old.. the scar now sits on/just below my rib cage. Problem is when I was pregnant it became very large and stretched. Now the incision has scar tissue and nerve issues. It protudes about 2 inches and when exercising that muscle tightens and is like a charley horse but in your side. I'm doing research to find out what it would take to fix it..
