In stage one of bed sores, the skin is not broken, but appears red and does not lighten when touched, says WebMD. The skin is usually hotter in this area and feels differently than the surrounding skin. In stage two, the skin breaks open and looks like a scrape, blister or a small depression. By stage three, the sore has reached the tissue under the skin, which may include fat tissue. In stage four, the sore has reached muscle and bone underneath the skin. Despite the severity of stages three and four, there may be little pain present due to the extent of tissue damage.

Sometimes a bed sore may damage the underlying tissue, but does not show as an open sore, according to WebMD. In these cases, the skin may be purple or dark red and a blister filled with blood may occur. Some other bed sores are covered by a layer of tissue and are hard to fit into one of the stages.
