Hi Since childhood i used to have lump on the left side of my forhead. In January 2020 i had this diagnosed as been scar tissue i was advised to have a steroid injection on the area to help flatten the lump i went ahead and had 1 treatment of this steroid injection in march 2020 in the next 2 weeks the lump disappeared but gradually over the following months it left me with this abnormal looking dented scar I want to know if i could get this to look better if i had scar revision surgery?
