Hi Dr. I do play a lot of contact competitive sports and also on the national team for kung fu. I get injured more often becuase of the vast majority of sports I compete at. Lately, my body is getting bruised up easily when I m getting hit or tackled and such. I m noticing that the bruises aren t going away and they are staying permanently. I have couple of bruises still to this day that I got in the past; one of them goes back to summer 2008 and its still showing as if i got hit recently. What is the cause of this? I ve also got some stitches in the past and the skin used to heal perfectly fine without even being able to see a scar. I ve got some stitches in last couple of months and it seems my skin started developing Cheloide after I healed and now its getting painful sometimes and it keeps building skin as if it looks swollen. I had 3 stitches. Whats going on with my body?
