Hi there, it sounds like you have some keloid scaring, I’m very prone to keloid scaring as my skin is very think and sensitive, iv been recommended by Mr Signh to buy silicone sheets and gels to use after op, and that is really good for scaring, researched it abit and found alot of people use it for their scaring and works really well, they are expensive to buy but u can get them cheaper on eBay. Iv heard the sheets are better then the gels. Hope this helps
