Is this a Normal C-Section?!?!?!

My mother had it kind of more than 30 years ago. She relates as to how difficult it is to heal the wound she got for having had a c-section. This is so because, the wound is deep, considerably deep. When our youngest sibling (a brother)was already more than 20 years old, she complained of how bad weather still affects the wound, caused her to feel some pain especially when there's lightning. She advised me never to have any operation unless it is necessary. From these conversations, I can say that it is true that, what you are going through now is normal under your condition.
