I developed a hematoma on my forehead 3 years ago after being kicked in the head. The swelling has subsided a bit over the years but it is still raised,discoloured and noticeable depending on the lighting . It has a raised scar running across it. I am prone to keloid scarring.When i touch the hematoma it feels a bit numb but it is also not hard. What are the options available to me to get rid of the hematoma and also the scar?
