Random bruising on your legs (as well as on other body parts) can cause unsightly skin discoloration as a result of a mild trauma or injury. Many people find that they have unexplained bruising on legs and want to know what causes bruises to appear for no apparent reason. Some people also bruise more easily than others and a seemingly insignificant knock may leave a black and blue dark patch on their skin.
Random or unexplained bruising on legs can happen for a number of reasons. For example, being in the sun too long, aging, or a vitamin deficiency can weaken small blood vessels near the skin’s surface. This can result in bruising easily on your legs or other areas of your body. Sometimes, bruising without an injury could be a sign of a serious underlying medical condition like diabetes, a blood clotting disorder, or an autoimmune disease.
In this article, you will find out what could be causing random bruising on your legs and other body parts, and in some cases, how to get rid of the bruise quickly. First of all, let’s look at what bruises are and what is the main cause of random bruising.
What Is a Bruise?
It’s very rare to have spontaneous bruising without any reason. People who are prone to bruising may not remember a minor trauma and assume that the bruise has appeared out of nowhere. Most bruising occurs as a result of some kind of injury.
Dr. John Cunha on eMedicineHealth explains that discoloration on the skin is caused by tiny blood vessels breaking under the skin. This causes blood from damaged veins and capillaries to collect near the surface of the skin. A bruise usually starts off as a black and blue patch of skin and gradually turns green or yellow as it heals.
You may find that the bruises on your body are painful at first but they may start to itch as they heal. Dr. Cunha says that it will take between one to two weeks for bruises to completely heal.
