I fell down on the road while jogging last month and hurt my knee. Now the scar is in red and brown color, feels very thick(raised) and sometimes gives me itches. This wound was having pus during the healing process but i had put Dettol antiseptic cream. I did not let the wound get contact with water at all for few weeks. Everything was fine, the dead cells peel off by itself. I had no idea what is causing it to be like that. Is there any way to improve this condition?
