I'm a bruiser, too! I certainly can't diagnose you, and recommend getting examined by a doctor, but I can tell you what diagnosis I had in the past. I was determined to be anemic, and the doctor would give me Vitamin B6 (or possibly B12, I forget which for sure) shots weekly (I think it was weekly, possibly a little less often). He said the shots worked a little better than vitamin pills, but I'm sure pills would work fine. Anyway, I might be anemic again, because I still bruise easily. I certainly don't have the best nutrition.

Try not to worry too much, because it might be something simply fixed with some vitamins. I get big bruises and little bruises, usually not knowing how or where I got them. I once had a pattern of bruises that looked like someone had grabbed me with their fingertips (which is a strange way to grab someone), and a friend got mad at me, claiming I was denying being abused by someone, LOL! But I wasn't abused at all.

Several weeks ago, I had a big, ugly bruise on my stomach (they're usually on my legs). I think I got it from bending over a box or possibly from our bathroom sink (I tend to lean against it when washing my hands). It was dark black and blue, purple, red, and all colors of the rainbow! Ick!
