Pigmentation or something else? I have old bruises on my legs, skin is smooth but bruises never fade - why?

I've had this problem for about 4 years now, and i don't even go to the pool anymore because I feel my legs (below the knee) look so ugly. The bruises are gone, if you can understand me - skin is smooth and in one piece - but the shape of the bruise and its dark brown colour - dont fade, as if to remind me everyday of the bruise I once had.
Is this an eating disorder? Is there a cream i can apply? What do I do? By the way, i am diabetic, but i don't believe this has anything to do with it? Or does it?

Having diabetes can cause problems with bruising or trouble with bruises going away because of diminished blood flow to the legs/circulation problems - the bruise is not able to be broken down and reabsorbed like it normally would be. My mom has a similar bruise on her leg - I remember her getting the bruise when I was about 10 and the spot is still brown like yours - almost 20 years later.

Possibly a vitamin K deficiency which causes high vulnerability to bruising. See doctor or nutritionist.

And it might very well be tied to your diabetic disorder.

being diabetic may have something to do with it see a dermatologist, I had surgery on my foot and ankle and when they removed the bandages 2weeks later alot of my skin from my ankle went with the bandage now I have a few dark brown spots where that happened,there not scars just dark spot, kinda looks like dirt, but my doc didnt know why that happened either!

Consistently bruising, and bruises that seem to never fade may be signs of other ailments, but you should definitely go to see a doctor just in case.
