Do you get bruises and have no recollection of how you got them? I usually get them on my legs and only notice when someone points it out to me. Last week I got a very dark and painful one on my arm, and I have no idea how I could not have hurt myself at the time.
Do you get unexplained bruises, and do you know what causes them?
When I was pregnant I used to bruise easily from things that shouldn't have caused bruising. I was very sick in my pregnancy and ended up with anemia and was told that this was causing me to bruise easily.
I think that the human body is an amazing thing and has it's way of telling us when something is not right. If you're bruising when you normally wouldn't, it's likely time to get checked out. If it's something like low iron, then it's worth getting this looked into so you can quickly remedy it.
When I was younger that would be the case and I had a check up and found out I was low in iron. Once I started iron supplements the mystery bruises magically disappeared. Good idea to check it out. Might be nothing but you never know.
