Also, this is probably me just worrying even more, but I have what I think is a splinter
hemorrhage on one finger nail. It's just one tiny brown line on one fingernail, so it could be because of trauma to my nail that I don't remember. I did some googling, and I'm worrying even more because I found out this is a symptom of endocarditis, inflammation of the valves of the heart. Could anyone have some advice to calm me down?
