There are Tiny Red Lines Under Your Fingernails
If you have small hemorrhages under your fingernails or toenails, and haven’t recently bumped or injured them, it could be a sign that something is not right.Tiny red streaks under your nails, also called splinter hemorrhages, are caused by broken blood vessels under the nail when small blood clots damage the capillaries. This can indicate a serious condition called endocarditis.
Endocarditis occurs when bacteria or other pathogens from one part of your body spread through the bloodstream and attach to the valves in your heart. Endocarditis, in its early stages, is treated with a simple course of antibiotics, however, if left untreated it can lead to life-threatening complications.
