My husband has got a scar on his chest following a pimple. Now, I feel that the size of the scar has become bigger than it was before. It is not painful, but he feels itchy sometimes. He has the scar for around three years now. He has a family history of keloid in his maternal grandmother and vitiligo in his maternal great grandmother. He was also treated for initial stage of vitiligo and got cured. I have attached the image. Please have a look. Thank you.
