I carry a lot of bruises on my legs since I have started biking again last year. I get them on my inner thighs from dismounting and from the knees down it looks like a war zone. I wish I didn't but I do. I also have a couple that have been there for over 6 months and have a knot in them. I asked the Dr. last time I was there for a check up and she said that sometimes when you bruise on the bone it might never go away!
